HTML <ul> class Attribute

The class attribute assigns one or more classnames to the <ul> 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 <ul> element.

  • Vincent Van Gogh
  • Paul Cézanne
  • Claude Monet
<style>
  .circles { list-style-type: circle; }
</style>

<ul class="circles">
  <li>Vincent Van Gogh</li>
  <li>Paul Cézanne</li>
  <li>Claude Monet</li>
</ul>

Using class

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

<ul class="classnames">

Values

More Examples

A class attribute styling a <ul> element.
Clicking the button toggles a classname that changes the item markers to square bullets.

  • Vincent Van Gogh
  • Paul Cézanne
  • Claude Monet

<style>
  .circles { list-style-type: circle; }
  .squares { list-style-type: square; }
</style>

<ul id="myul" class="circles">
  <li>Vincent Van Gogh</li>
  <li>Paul Cézanne</li>
  <li>Claude Monet</li>
</ul>

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

<script>
  let toggle = () => {
     let element = document.getElementById("myul");
     element.classList.toggle("squares");
  }
</script>

Code explanation

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

The class attribute in <ul> assigns one classname.

Repeatedly clicking the button toggles another class, changing the style of the <ul> bullets.
