HTML <caption> class Attribute

The class attribute assigns one or more classnames to the <caption> tag.

Classnames are defined in a stylesheet or in a local <style> element.

Classes, i.e. classnames, are used to style the caption element.

Using class

Classes (i.e. classnames) are used for styling the caption element.

Multiple classnames are separated by a space.

JavaScript uses classes to access elements by classname.

Tip:  class is a global attribute that can be applied to any HTML element.


Syntax

<caption class="classnames" >

 .tb th, .tb td { padding:3px; border: 1px solid #777; }
 .caption-lightblue { background-color:lightblue; color:black; padding:5px; }
 .caption-papayawhip { background-color:papayawhip; }
</style>

<table class="tb">
  <caption class="caption-lightblue" 
           id="mycaption">Artists</caption>
  <tr> 
    <th>Firstname</th>
    <th>Lastname</th>
    <th>Country</th>
  </tr>
  <tr> 
    <td>Vincent</td>
    <td>Van Gogh</td>
    <td>Netherlands</td>
  </tr>
  <tr> 
    <td>Paul</td>
    <td>Cézanne</td>
    <td>France</td>
  </tr>
</table>

<br/>
<button type="button" onclick="toggle();">Toggle class</button>

<script>
  let toggle = () => {
    let element = document.getElementById("mycaption");
    element.classList.toggle("caption-papayawhip");
  }
</script>

Code explanation

Two CSS classes are defined in the <style> element.

The class attribute in <caption> assigns one classname.

Clicking the button calls JavaScript which toggles another class changing the caption background color.
