HTML <figcaption> class Attribute

HTML <fieldset>

HTML <figure>

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

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

Classes, i.e. classnames, are used to style elements.

Example

#

A class attribute styling a <figcaption> element.

<style>
  .fig {color:teal; font-style:italic; font-size:20px; }
</style>

<figure>
  <img src="/img/html/sangiorgio.jpg">
  <figcaption class="fig">A Beautiful Oil Painting</figcaption>
</figure>

Using class

#

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

<figcaption class="classnames">

More Examples

#

A class attribute styling a <figcaption> element.
Clicking the button toggles a classname that adds an underline.

<style>
  .figcaption {color:teal; font-style:italic; font-size:20px; }
  .fc-underline { text-decoration: underline; }
</style>

<figure>
  <img src="/img/html/sangiorgio.jpg">
  <figcaption id="myfigcaption" class="figcaption">
    A Beautiful Oil Painting
  </figcaption>
</figure>

<br/>
<button onclick="toggle();">Toggle class</button>

<script>
  let toggle = () => {
    let element = document.getElementById("myfigcaption");
    element.classList.toggle("fc-underline");
  }
</script>

Code explanation

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

The class attribute in <figcaption> assigns two from those.

Repeatedly clicking the button toggles the third class, changing the text decoration of the <figcaption>.
