HTML <colgroup> Tag
Description
The <colgroup>
HTML element is intended to specify the width and style of one or more columns of the table. This element allows you to reduce the code of the table by reducing duplicate attributes, and if it is available, the browser starts showing the contents of the table, without waiting for it to fully load. The <colgroup>
element can be used in combination with <col>
, which defines the characteristics of one or more columns.
Usually, a closing tag is not required, but if the <colgroup>
acts as a container for the <col>
elements, then the </colgroup> tag should be added at the end of the group.
Properties
- Permitted Parents
- A <table> element. The <colgroup> must appear after any optional <caption> element but before any <thead>, <th>, <tbody>, <tfoot> and <tr> element.
- Content
- 0 or more <col> elements
- Start/End Tags
