HTML Introduction[top]

What is HTML?

HTML is a language for describing web pages.
• HTML stands for Hyper Text Markup Language
• HTML is not a programming language, it is a markup language
• A markup language is a set of markup tags
• HTML uses markup tags to describe web pages


HTML Tags

HTML markup tags are usually called HTML tags

• HTML tags are keywords surrounded by angle brackets like < html>
• HTML tags normally come in pairs like < b> and < /b>
• The first tag in a pair is the start tag, the second tag is the end tag
• Start and end tags are also called opening tags and closing tags


HTML Documents = Web Pages

• HTML documents describe web pages
• HTML documents contain HTML tags and plain text
• HTML documents are also called web pages

The purpose of a web browser (like Internet Explorer or Firefox) is to read HTML documents and display them as web pages. The browser does not display the HTML tags, but uses the tags to interpret the content of the page:


< html>
< body>
< h1>My First Heading< /h1>
< p>My first paragraph.< /p>
< /body>
< /html>

Example Explained

• The text between < html> and < /html> describes the web page • The text between < body> and < /body> is the visible page content • The text between < h1> and < /h1> is displayed as a heading • The text between < p> and < /p> is displayed as a paragraph

What You Need[top]

You don't need any tools to learn HTML at W3Schools.

• You don't need an HTML editor
• You don't need a web server
• You don't need a web site

Editing HTML

HTML can be written and edited using many different editors like Dreamweaver and Visual Studio.
However, in this tutorial we use a plain text editor (like Notepad) to edit HTML. We believe using a plain text editor is the best way to learn HTML.


Create Your Own Test Web

If you just want to learn HTML, skip the rest of this chapter.
If you want to create a test page on your own computer, just copy the 3 files below to your desktop.
(Right click on each link, and select "save target as" or "save link as")
mainpage.htm
page1.htm
page2.htm
After you have copied the files, you can double-click on the file called "mainpage.htm" and see your first web site in action.


Use Your Test Web For Learning

We suggest you experiment with everything you learn at W3Schools by editing your web files with a text editor (like Notepad). Note: If your test web contains HTML markup tags you have not learned, don't panic. You will learn all about it in the next chapters.


.HTM or .HTML File Extension?

When you save an HTML file, you can use either the .htm or the .html file extension. There is no difference, it is entirely up to you.



HTML Basic - 4 Examples[top]

Don't worry if the examples use tags you have not learned. You will learn about them in the next chapters.

HTML Headings

HTML headings are defined with the < h1> to < h6> tags.


HTML Paragraphs

HTML paragraphs are defined with the < p> tag.< /p>

HTML Links

HTML links are defined with the < a> tag.
< a href="http://www.w3schools.com">This is a link< /a>
Note: The link address is specified in the href attribute. (You will learn about attributes in a later chapter of this tutorial).


HTML Images

HTML images are defined with the < img> tag.
< img src="w3schools.jpg" width="104" height="142" />
Note: The name and the size of the image are provided as attributes.



HTML Elements[top]

HTML documents are defined by HTML elements.


HTML Elements

An HTML element is everything from the start tag to the end tag:

Start tag * Element content End tag *
< p> This is a paragraph < /p>
< a href="default.htm" > This is a link < /a>
< br />/td>    

* The start tag is often called the opening tag. The end tag is often called the closing tag.


HTML Element Syntax

• An HTML element starts with a start tag / opening tag
• An HTML element ends with an end tag / closing tag
• The element content is everything between the start and the end tag
• Some HTML elements have empty content
• Empty elements are closed in the start tag
• Most HTML elements can have attributes

Tip: You will learn about attributes in the next chapter of this tutorial.


Nested HTML Elements

Most HTML elements can be nested (can contain other HTML elements).
HTML documents consist of nested HTML elements.


HTML Document Example

< html>

< body>
< p>This is my first paragraph.< /p>
< /body>
< /html>


The example above contains 3 HTML elements.


HTML Example Explained

The < p> element:

< p>This is my first paragraph.< /p>

The < p> element defines a paragraph in the HTML document. The element has a start tag < p> and an end tag < /p>. The element content is: This is my first paragraph.


The < body> element:

< body>
< p>This is my first paragraph.< /p>
< /body>

The < body> element defines the body of the HTML document. The element has a start tag < body> and an end tag < /body>. The element content is another HTML element (a p element).


The < html> element:

< html>

< body>
< p>This is my first paragraph.< /p>
< /body>

< /html>


The < html> element defines the whole HTML document. The element has a start tag < html> and an end tag < /html>. The element content is another HTML element (the body element).


Don't Forget the End Tag

Some HTML elements might display correctly even if you forget the end tag:

< p>This is a paragraph
< p>This is a paragraph

The example above works in most browsers, because the closing tag is considered optional.

Never rely on this. Many HTML elements will produce unexpected results and/or errors if you forget the end tag .


Empty HTML Elements

HTML elements with no content are called empty elements.

< br> is an empty element without a closing tag (the < br> tag defines a line break).

Tip: In XHTML, all elements must be closed. Adding a slash inside the start tag, like < br />, is the proper way of closing empty elements in XHTML (and XML).


HTML Tip: Use Lowercase Tags

HTML tags are not case sensitive: < P> means the same as < p>. Many web sites use uppercase HTML tags. W3Schools use lowercase tags because the World Wide Web Consortium (W3C) recommends lowercase in HTML 4, and demands lowercase tags in XHTML.



Ref: http://www.w3schools.com/html/html_attributes.asp

HTML Attributes [top]

Attributes provide additional information about HTML elements.

HTML Attributes

• HTML elements can have attributes
Attributes provide additional information about an element
Attributes are always specified in the start tag
Attributes come in name/value pairs like: name="value"

Attribute Example

HTML links are defined with the tag. The link address is specified in the href attribute:

< a href="http://www.w3schools.com">This is a link< /a>


Always Quote Attribute Values

Attribute values should always be enclosed in quotes.
Double style quotes are the most common, but single style quotes are also allowed.

Tip: In some rare situations, when the attribute value itself contains quotes, it is necessary to use single quotes: name='John "ShotGun" Nelson'

HTML Tip: Use Lowercase Attributes

Attribute names and attribute values are case-insensitive.
However, the World Wide Web Consortium (W3C) recommends lowercase attributes/attribute values in their HTML 4 recommendation.


Newer versions of (X)HTML will demand lowercase attributes.

HTML Attributes Reference

A complete list of legal attributes for each HTML element is listed in our:
Complete HTML Reference
Below is a list of some attributes that are standard for most HTML elements:

Attribute Value Description
class classname Specifies a classname for an element
id id Specifies a unique id for an element
style style_definition Specifies an inline style for an element
title tooltip_text Specifies extra information about an element (displayed as a tool tip)

For more information about standard attributes:
HTML Standard Attributes Reference

HTML Headings [top]

Headings are important in HTML documents.


HTML Headings

Headings are defined with the < h1> to < h6> tags. < h1> defines the most important heading. < h6> defines the least important heading. Example

< h1>This is a heading< /h1>
< h2>This is a heading< /h2>
< h3>This is a heading< /h3>


Note: Browsers automatically add some empty space (a margin) before and after each heading.


Headings Are Important

Use HTML headings for headings only. Don't use headings to make text BIG or bold.
Search engines use your headings to index the structure and content of your web pages.
Since users may skim your pages by its headings, it is important to use headings to show the document structure.
H1 headings should be used as main headings, followed by H2 headings, then the less important H3 headings, and so on.


HTML Lines

The < hr /> tag creates a horizontal line in an HTML page. The hr element can be used to separate content:

< p>This is a paragraph< /p>
< hr />
< p>This is a paragraph< /p>
< hr />
< p>This is a paragraph < /p>



HTML Comments

Comments can be inserted into the HTML code to make it more readable and understandable. Comments are ignored by the browser and are not displayed.
Comments are written like this:
Example

< !-- This is a comment -->

Note: There is an exclamation point after the opening bracket, but not before the closing bracket.


HTML Tip - How to View HTML Source

Have you ever seen a Web page and wondered "Hey! How did they do that?"
To find out, right-click in the page and select "View Source" (IE) or "View Page Source" (Firefox), or similar for other browsers. This will open a window containing the HTML code of the page.


HTML Tag Reference

W3Schools' tag reference contains additional information about these tags and their attributes.
You will learn more about HTML tags and attributes in the next chapters of this tutorial.

Tag Description
< html> Defines an HTML document
< body> Defines the document's body
< h1> to < h6> < h1> to < h6>
< hr /> Defines a horizontal line
< !--> Defines a comment


Ref: http://www.w3schools.com/html/html_paragraphs.asp

HTML Paragraphs [top]

HTML documents are divided into paragraphs.


HTML Paragraphs

Paragraphs are defined with the < p> tag.

< p>This is a paragraph< /p>
< p>This is another paragraph< /p>

Note: Browsers automatically add an empty line before and after a paragraph.

Don't Forget the End Tag


< p>This is a paragraph
< p>This is another paragraph

The example above will work in most browsers, but don't rely on it. Forgetting the end tag can produce unexpected results or errors.

Note: Future version of HTML will not allow you to skip end tags.


HTML Line Breaks

Use the < br /> tag if you want a line break (a new line) without starting a new paragraph:< /p> < p>This is< br />a para< br />graph with line breaks< /p>

The < br /> element is an empty HTML element. It has no end tag.

< br> or < br />

In XHTML, XML, elements with no end tag (closing tag) are not allowed. Even if < br> works in all browsers, writing < br /> instead works better in XHTML and XML applications.


HTML Output - Useful Tips

You cannot be sure how HTML will be displayed. Large or small screens, and resized windows will create different results.

With HTML, you cannot change the output by adding extra spaces or extra lines in your HTML code.
The browser will remove extra spaces and extra lines when the page is displayed. Any number of lines count as one line, and any number of spaces count as one space.


HTML Tag Reference

W3Schools' tag reference contains additional information about HTML elements and their attributes.

Tag Description
< p> Defines a paragraph
< br /> Inserts a single line break



ref: http://www.w3schools.com/html/html_formatting.asp

HTML Text Formatting [top]

HTML Formatting Tags

HTML uses tags like < b> and < i> for formatting output, like bold or italic text.
These HTML tags are called formatting tags (look at the bottom of this page for a complete reference).
Often < strong> renders as < b>, and < em> renders as < i>.
However, there is a difference in the meaning of these tags:
< b> or < i> defines bold or italic text only. < strong> or < em> means that you want the text to be rendered in a way that the user undestrongrstands as "important". Today, all major browsers render strong as bold and em as italics. However, if a browser one day wants to make a text highlighted with the strong feature, it might be cursive for example and not bold!

HTML Fonts [top]

The HTML < font> Tag Should NOT be Used

The < font> tag is deprecated in HTML 4, and removed from HTML5.
The World Wide Web Consortium (W3C) has removed the < font> tag from its recommendations.
In HTML 4, style sheets (CSS) should be used to define the layout and display properties for many HTML elements.
The example below shows how the HTML could look by using the < font> tag:


< p>
< font size="5" face="arial" color="red">
This paragraph is in Arial, size 5, and in red text color.
< /font>
< /p>

< p>
< font size="3" face="verdana" color="blue">
This paragraph is in Verdana, size 3, and in blue text color. < /font>
< /p>

HTML Styles - CSS [top]

CSS is used to style HTML elements.
Because this is the subject of this whole website, I will omit this section.



Ref: http://www.w3schools.com/html/html_links.asp

HTML Links [top]

Links are found in nearly all Web pages. Links allow users to click their way from page to page.


HTML Hyperlinks (Links)

A hyperlink (or link) is a word, group of words, or image that you can click on to jump to a new document or a new section within the current document.
When you move the cursor over a link in a Web page, the arrow will turn into a little hand.
Links are specified in HTML using the < a> tag.
The < a> tag can be used in two ways:
1. To create a link to another document, by using the href attribute
2. To create a bookmark inside a document, by using the name attribute


HTML Link Syntax

The HTML code for a link is simple. It looks like this:
< a href="url">Link text< /a>
The href attribute specifies the destination of a link.


Example

< a href="http://www.w3schools.com/">Visit W3Schools < /a> which will display like this: Visit W3Schools (underlined)
Clicking on this hyperlink will send the user to W3Schools' homepage.
Tip: The "Link text" doesn't have to be text. It can be an image or any other HTML element.


HTML Links - The target Attribute

The target attribute specifies where to open the linked document.
The example below will open the linked document in a new browser window or a new tab:

< a href="http://www.w3schools.com/" target="_blank">Visit W3Schools!< /a>


HTML Links - The name Attribute

The name attribute specifies the name of an anchor.

The name attribute is used to create a bookmark inside an HTML document.

Note: The upcoming HTML5 standard suggest using the id attribute instead of the name attribute for specifying the name of an anchor. Using the id attribute actually works also for HTML4 in all modern browsers.

Bookmarks are not displayed in any special way. They are invisible to the reader.

A named anchor inside an HTML document:
< a name="tips">Useful Tips Section< /a>
Create a link to the "Useful Tips Section" inside the same document:
< a href="#tips">
Visit the Useful Tips Section< /a>

Or, create a link to the "Useful Tips Section" from another page:
< a href="http://www.w3schools.com/html_links.htm#tips">
Visit the Useful Tips Section< /a>


Basic Notes - Useful Tips

Note: Always add a trailing slash to subfolder references. If you link like this:
href="http://www.w3schools.com/html",
you will generate two requests to the server, the server will first add a slash to the address, and then create a new request like this:
href="http://www.w3schools.com/html/".

Tip: Named anchors are often used to create "table of contents" at the beginning of a large document. Each chapter within the document is given a named anchor, and links to each of these anchors are put at the top of the document.

HTML Images [top]


HTML Images - The < img> Tag and the Src Attribute

In HTML, images are defined with the < img> tag.
The < img> tag is empty, which means that it contains attributes only, and has no closing tag.
To display an image on a page, you need to use the src attribute. Src stands for "source". The value of the src attribute is the URL of the image you want to display.


Syntax for defining an image:
< img src="url" alt="some_text"/>

The URL points to the location where the image is stored. An image named "boat.gif", located in the "images" directory on "www.w3schools.com" has the URL:
http://www.w3schools.com/images/boat.gif.

The browser displays the image where the < img> tag occurs in the document. If you put an image tag between two paragraphs, the browser shows the first paragraph, then the image, and then the second paragraph.


HTML Images - The Alt Attribute

The required alt attribute specifies an alternate text for an image, if the image cannot be displayed.
The value of the alt attribute is an author-defined text:
< img src="boat.gif" alt="Big Boat" />
The alt attribute provides alternative information for an image if a user for some reason cannot view it (because of slow connection, an error in the src attribute, or if the user uses a screen reader).

HTML Images - Set Height and Width of an Image

The height and width attributes are used to specify the height and width of an image.
The attribute values are specified in pixels by default:
< img src="pulpit.jpg" alt="Pulpit rock" width="304" height="228" />
Tip: It is a good practice to specify both the height and width attributes for an image. If these attributes are set, the space required for the image is reserved when the page is loaded. However, without these attributes, the browser does not know the size of the image. The effect will be that the page layout will change during loading (while the images load).


Basic Notes - Useful Tips

Note: If an HTML file contains ten images - eleven files are required to display the page right. Loading images take time, so my best advice is: Use images carefully.

Note: When a web page is loaded, it is the browser, at that moment, that actually gets the image from a web server and inserts it into the page. Therefore, make sure that the images actually stay in the same spot in relation to the web page, otherwise your visitors will get a broken link icon. The broken link icon is shown if the browser cannot find the image.

HTML Tables [top]

How to specify different table borders:

First Row
Second Row

< table border="15">
< tr>
< td>First< /td>
< td>Row< /td>
< /tr>
< tr>
< td>Second< /td>
< td>Row< /td>
< /tr>
< /table>



Tables are defined with the < table> tag. A table is divided into rows (with the < tr> tag), and each row is divided into data cells (with the < td> tag). td stands for "table data," and holds the content of a data cell. A < td> tag can contain text, links, images, lists, forms, other tables, etc.

Table Example

< table border="1">
< tr>
< td>row 1, cell 1< /td>
< td>row 1, cell 2< /td>
< /tr>
< tr>
< td>row 2, cell 1 < /td>
< td>row 2, cell 2< /td>
< /tr>
< /table>
row 1, cell 1 row 1, cell 2
row 2, cell 1 row 2, cell 2



HTML Tables and the Border Attribute

If you do not specify a border attribute, the table will be displayed without borders. Sometimes this can be useful, but most of the time, we want the borders to show.

To display a table with borders, specify the border attribute (see above).

HTML Table Headers

Header information in a table are defined with the < th> tag.
All major browsers will display the text in the < th> element as bold and centered.

< table border="1">
< tr>
< th>Header 1< /th>
< th>Header 2< /th>
< /tr>
< tr>
< td>row 1, cell 1< /td>
< td>row 1, cell 2< /td>
< /tr>
< tr>
< td>row 2, cell 1< /td>
< td>row 2, cell 2< /td>
< /tr>
< /table>


Header 1 Header 2
row 1, cell 1 row 1, cell 2
row 2, cell 1 row 2, cell 2

HTML Lists [top]


The most common HTML lists are ordered and unordered lists:

An Unordered List:

< h4>An Unordered List:< /h4>
< ul>
< li>Coffee< /li>
< li>Tea< /li>
< li>Milk< /li>
< /ul>



An Ordered List:

  1. Coffee
  2. Tea
  3. Milk
< h4>An Ordered List:< /h4>
< ol>
< li>Coffee< /li>
< li>Tea< /li>
< li>Milk< /li>
< /ol>



HTML Unordered Lists

An unordered list starts with the < ul> tag. Each list item starts with the < li> tag.
The list items are marked with bullets (typically small black circles).

< ul>
< li>Coffee< /li>
< li>Milk< /li>
< /ul>


HTML Ordered Lists

An ordered list starts with the < ol> tag. Each list item starts with the < li> tag.
The list items are marked with numbers.

< ol>
< li>Coffee< /li>
< li>Milk< /li>
< /ol>


HTML Definition Lists

A definition list is a list of items, with a description of each item.
The < dl> tag defines a definition list. The < dl> tag is used in conjunction with < dt> (defines the item in the list) and < dd> (describes the item in the list):

Coffee
- black hot drink
Milk
- white cold drink
< dl>
< dt>Coffee< /dt>
< dd>- black hot drink< /dd>
< dt>Milk< /dt>
< dd>- white cold drink< /dd>

HTML Forms

HTML forms are used to pass data to a server.
A form can contain input elements like text fields, checkboxes, radio-buttons, submit buttons and more. A form can also contain select lists, textarea, fieldset, legend, and label elements.
The < form> tag is used to create an HTML form:

< form>
.
input elements
.
< /form>


HTML Forms - The Input Element

The most important form element is the input element.
The input element is used to select user information.
An input element can vary in many ways, depending on the type attribute. An input element can be of type text field, checkbox, password, radio button, submit button, and more.
The most used input types are described below:

Text Fields

< input type="text" /> defines a one-line input field that a user can enter text into:

< form>
First name: < input type="text" name="firstname" />< br />
Last name: < input type="text" name="lastname" />
< /form>

How the HTML code above looks in a browser:

First name:
Last name:

Note: The form itself is not visible. Also note that the default width of a text field is 20 characters.



Password Field

< input type="password" /> defines a password field:

< form>
Password: < input type="password" name="pwd" />
< /form>

How the HTML code above looks in a browser:

Password:

Note: The characters in a password field are masked (shown as asterisks or circles).



Radio Buttons

< input type="radio" /> defines a radio button. Radio buttons let a user select ONLY ONE of a limited number of choices:

< form>
< input type="radio" name="sex" value="male" /> Male< br />
< input type="radio" name="sex" value="female" /> Female
< /form>

How the HTML code above looks in a browser:

Male
Female


Checkboxes

< input type="checkbox" /> defines a checkbox. Checkboxes let a user select ONE or MORE options of a limited number of choices.

< form>
< input type="checkbox" name="vehicle" value="Bike" /> I have a bike< br />
< input type="checkbox" name="vehicle" value="Car" /> I have a car
< /form>

How the HTML code above looks in a browser:

I have a bike
I have a car



Submit Button

< input type="submit" /> defines a submit button.

A submit button is used to send form data to a server. The data is sent to the page specified in the form's action attribute. The file defined in the action attribute usually does something with the received input:

< form name="input" action="html_form_action.asp" method="get">
Username: < input type="text" name="user" />
< input type="submit" value="Submit" />
< /form>

How the HTML code above looks in a browser:

Username:

If you type some characters in the text field above, and click the "Submit" button, the browser will send your input to a page called "html_form_action.asp". The page will show you the received input.

HTML Frames [top]

With frames, several Web pages can be displayed in the same browser window.
ATTENTION. Do not expect frames to be supported in future versions of HTML.

With frames, you can display more than one HTML document in the same browser window. Each HTML document is called a frame, and each frame is independent of the others.
The disadvantages of using frames are:
• Frames are not expected to be supported in future versions of HTML
• Frames are difficult to use. (Printing the entire page is difficult).
• The web developer must keep track of more HTML documents


The HTML frameset Element

The frameset element holds one or more frame elements. Each frame element can hold a separate document.

The frameset element states HOW MANY columns or rows there will be in the frameset, and HOW MUCH percentage/pixels of space will occupy each of them.



The HTML frame Element

The < frame> tag defines one particular window (frame) within a frameset.
In the example below we have a frameset with two columns.
The first column is set to 25% of the width of the browser window. The second column is set to 75% of the width of the browser window. The document "frame_a.htm" is put into the first column, and the document "frame_b.htm" is put into the second column:
< frameset cols="25%,75%">
< frame src="frame_a.htm" />
< frame src="frame_b.htm" />
< /frameset>

Note: The frameset column size can also be set in pixels (cols="200,500"), and one of the columns can be set to use the remaining space, with an asterisk (cols="25%,*").

Basic Notes - Useful Tips

Tip: If a frame has visible borders, the user can resize it by dragging the border. To prevent a user from doing this, you can add noresize="noresize" to the < frame> tag.
Note: Add the < noframes> tag for browsers that do not support frames.
Important: You cannot use the < body>< /body> tags together with the < frameset>< /frameset> tags! However, if you add a < noframes> tag containing some text for browsers that do not support frames, you will have to enclose the text in < body>< /body> tags! See how it is done in the first example below.

More Examples

How to use the < noframes> tag (for browsers that do not support frames).


HTML Frame Tags

Tag Description
< frameset> Defines a set of frames
< frame /> Defines a sub window (a frame)
< noframes> Defines a noframe section for browsers that do not handle frames

Ref: http://www.w3schools.com/html/html_iframe.asp

HTML Iframes [top]

An iframe is used to display a web page within a web page.

Syntax for adding an iframe:
< iframe src="URL">< /iframe>
The URL points to the location of the separate page.

Iframe - Set Height and Width

The height and width attributes are used to specify the height and width of the iframe.
The attribute values are specified in pixels by default, but they can also be in percent (like "80%").
Example
< iframe src="demo_iframe.htm" width="200" height="200">< /iframe>

Some older browsers don't support iframes.

If they don't, the iframe will not be visible.


< iframe src="demo_iframe.htm" width="200" height="200">< /iframe>
< p>Some older browsers don't support iframes.< /p>
< p>If they don't, the iframe will not be visible.< /p>




Iframe - Remove the Border

The frameborder attribute specifies whether or not to display a border around the iframe.
Set the attribute value to "0" to remove the border:
Example
< iframe src="demo_iframe.htm" frameborder="0">< /iframe>

Some older browsers don't support iframes.

If they don't, the iframe will not be visible.

< iframe src="demo_iframe.htm" frameborder="0">< /iframe>
< p>Some older browsers don't support iframes.< /p>
< p>If they don't, the iframe will not be visible.< /p>



Use iframe as a Target for a Link

An iframe can be used as the target frame for a link.
The target attribute of a link must refer to the name attribute of the iframe:
Example
< iframe src="demo_iframe.htm" name="iframe_a">< /iframe>
< p>< a href="http://www.w3schools.com" target="iframe_a">W3Schools.com< /a>< /p>

W3Schools.com

Note: Because the target of the link matches the name of the iframe, the link will open in the iframe.

HTML iframe Tag

Tag Description
<iframe> Defines an inline sub window (frame)

Ref: http://www.w3schools.com/html/html_colors.asp
Colors are displayed combining RED, GREEN, and BLUE light.

Colors in HTML - Color Values [top]

HTML colors are defined using a hexadecimal notation (HEX) for the combination of Red, Green, and Blue color values (RGB).
The lowest value that can be given to one of the light sources is 0 (in HEX: 00). The highest value is 255 (in HEX: FF).
HEX values are specified as 3 pairs of two-digit numbers, starting with a # sign.

Color Values

Color Color HEX Color HEX
#000000 rgb(0,0,0)
  #FF0000 rgb(255,0,0)
  #00FF00 rgb(0,255,0)
  #0000FF rgb(0,0,255)
  #FFFF00 rgb(255,255,0)
  #00FFFF rgb(0,255,255)
  #FF00FF rgb(255,0,255)
  #C0C0C0 rgb(192,192,192)
 

#FFFFFF

rgb(255,255,255)


Example

Color set by using color name

< p style="background-color:yellow">
Color set by using color name < /p>



16 Million Different Colors

The combination of Red, Green, and Blue values from 0 to 255, gives more than 16 million different colors (256 x 256 x 256).
If you look at the color table below, you will see the result of varying the red light from 0 to 255, while keeping the green and blue light at zero.
To see the full list of color mixes when RED varies from 0 to 255, click on one of the HEX or RGB values below.

Note: To colour a cell a particular colour, use the background color instruction:
< td bgcolor="#400000"> < /td>

Shades of Gray

Gray colors are created by using an equal amount of power to all of the light sources.
To make it easier for you to select the correct shade, we have created a table of gray shades for you:
Fpr example:

#282828    rgb(40,40,40)
#303030    rgb(48,48,48)


Web Safe Colors?

Some years ago, when computers supported max 256 different colors, a list of 216 "Web Safe Colors" was suggested as a Web standard, reserving 40 fixed system colors.
The 216 cross-browser color palette was created to ensure that all computers would display the colors correctly when running a 256 color palette.
This is not important today, since most computers can display millions of different colors.
