totn HTML HTML: <col> tag

This HTML tutorial explains how to use the HTML element called the <col> tag with syntax and examples.

Description

The HTML <col> tag defines properties for columns within the <colgroup> tag. This allows you to apply formatting or add classes to a column or group of columns instead of each individual cell. This tag is also commonly referred to as the <col> element.

Syntax

In HTML, the syntax for the <col> tag is: (example of a table where the first three columns have a light orange background color of #FFF3E0 and the last column has an orange background)

<body> <table> <colgroup> <col span="3" style="background-color:#FFF3E0;"> <col style="background-color:orange;"> </colgroup> <thead> <tr> <th>Item</th> <th>Quantity</th> <th>Price</th> <th>Total</th> </tr> </thead> <tbody> <tr> <td>Oranges</td> <td>45</td> <td>$2</td> <td>$90</td> </tr> </tbody> </table> </body>

Example

We will discuss the <col> tag below, exploring examples of how to use the <col> tag in HTML5, HTML 4.01 Transitional, XHTML 1.0 Transitional, XHTML 1.0 Strict, and XHTML 1.1.

  • HTML5
  • HTML4
  • XHTML

HTML5 Document

If you created a new web page in HTML5, your <col> tag might look like this:

<!doctype html> <html> <head> <meta charset="UTF-8"> <title>HTML5 Example by www.techonthenet.com</title> </head> <body> <table> <colgroup> <col span="3" style="background-color:#FFF3E0;"> <col style="background-color:orange;"> </colgroup> <thead> <tr> <th>Item</th> <th>Quantity</th> <th>Price</th> <th>Total</th> </tr> </thead> <tbody> <tr> <td>Oranges</td> <td>45</td> <td>$2</td> <td>$90</td> </tr> </tbody> </table> </body> </html>

In this HTML5 Document example, we have created a table with <colgroup>, <thead> and <tbody> sections. Within the <colgroup> section, we've used two <col> tags. The first <col> tag groups the first three columns and sets the background color of the columns to a light orange color which is the hexadecimal value of #FFF3E0. The second <col> tag groups the 4th column and sets its background color to orange.

HTML 4.01 Transitional Document

If you created a new web page in HTML 4.01 Transitional, your <col> tag might look like this:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>HTML 4.01 Transitional Example by www.techonthenet.com</title> </head> <body> <table> <colgroup> <col span="3" style="background-color:#FFF3E0;"> <col style="background-color:orange;"> </colgroup> <thead> <tr> <th>Item</th> <th>Quantity</th> <th>Price</th> <th>Total</th> </tr> </thead> <tbody> <tr> <td>Oranges</td> <td>45</td> <td>$2</td> <td>$90</td> </tr> </tbody> </table> </body> </html>

In this HTML 4.01 Transitional Document example, we have created a table with <colgroup>, <thead> and <tbody> sections. Within the <colgroup> section, we've used two <col> tags. The first <col> tag groups the first three columns and sets the background color of the columns to a light orange color which is the hexadecimal value of #FFF3E0. The second <col> tag groups the 4th column and sets its background color to orange.

XHTML 1.0 Transitional Document

If you created a new web page in XHTML 1.0 Transitional, your <col> tag might look like this:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>XHMTL 1.0 Transitional Example by www.techonthenet.com</title> </head> <body> <table> <colgroup> <col span="3" style="background-color:#FFF3E0;" /> <col style="background-color:orange;" /> </colgroup> <thead> <tr> <th>Item</th> <th>Quantity</th> <th>Price</th> <th>Total</th> </tr> </thead> <tbody> <tr> <td>Oranges</td> <td>45</td> <td>$2</td> <td>$90</td> </tr> </tbody> </table> </body> </html>

In this XHTML 1.0 Transitional Document example, we have created a table with <colgroup>, <thead> and <tbody> sections. Within the <colgroup> section, we've used two <col> tags. The first <col> tag groups the first three columns and sets the background color of the columns to a light orange color which is the hexadecimal value of #FFF3E0. The second <col> tag groups the 4th column and sets its background color to orange.

XHTML 1.0 Strict Document

If you created a new web page in XHTML 1.0 Strict, your <col> tag might look like this:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>XHTML 1.0 Strict Example by www.techonthenet.com</title> </head> <body> <table> <colgroup> <col span="3" style="background-color:#FFF3E0;" /> <col style="background-color:orange;" /> </colgroup> <thead> <tr> <th>Item</th> <th>Quantity</th> <th>Price</th> <th>Total</th> </tr> </thead> <tbody> <tr> <td>Oranges</td> <td>45</td> <td>$2</td> <td>$90</td> </tr> </tbody> </table> </body> </html>

In this XHTML 1.0 Strict Document example, we have created a table with <colgroup>, <thead> and <tbody> sections. Within the <colgroup> section, we've used two <col> tags. The first <col> tag groups the first three columns and sets the background color of the columns to a light orange color which is the hexadecimal value of #FFF3E0. The second <col> tag groups the 4th column and sets its background color to orange.

XHTML 1.1 Document

If you created a new web page in XHTML 1.1, your <col> tag might look like this:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>XHTML 1.1 Example by www.techonthenet.com</title> </head> <body> <table> <colgroup> <col span="3" style="background-color:#FFF3E0;" /> <col style="background-color:orange;" /> </colgroup> <thead> <tr> <th>Item</th> <th>Quantity</th> <th>Price</th> <th>Total</th> </tr> </thead> <tbody> <tr> <td>Oranges</td> <td>45</td> <td>$2</td> <td>$90</td> </tr> </tbody> </table> </body> </html>

In this XHTML 1.1 Document example, we have created a table with <colgroup>, <thead> and <tbody> sections. Within the <colgroup> section, we've used two <col> tags. The first <col> tag groups the first three columns and sets the background color of the columns to a light orange color which is the hexadecimal value of #FFF3E0. The second <col> tag groups the 4th column and sets its background color to orange.
