HTML5 <col> tag


May 03, 2021 13:20 HTML5


Table of contents


HTML5 labels are used to control the columns in the table, making it easier for you to style the columns in the table.

The labels set the background color for the three columns in the table:

<table border="1">
  <colgroup>
    <col span="2" style="background-color:red">
    <col style="background-color:yellow">
  </colgroup>
  <tr>
    <th>ISBN</th>
    <th>Title</th>
    <th>Price</th>
  </tr>
  <tr>
    <td>3476896</td>
    <td>My first HTML</td>
    <td>$53</td>
  </tr>
</table>
