HTML <code> class Attribute

The class attribute on a <code> tag assigns one or more classnames to the code element. Classes are used to style elements. Classnames are defined in a stylesheet or in a local <style> element.

Example

#

A class attribute styling a <code> element.

In JavaScript the alert() method displays an alert box.

<style>
  .code-underline {text-decoration: underline;}
</style>

<p>
  In JavaScript the 
  <code class="code-underline">alert()</code> 
  method displays an alert box.
</p>

Using class

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

Multiple classnames are separated by a space.

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

JavaScript uses classes to access one or more elements by classname.

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

More Examples

A class attribute styling a <code> element.
Clicking the button toggles a classname that changes the underlining.

In JavaScript the alert() method displays an alert box.

<style>
  .code-underline { text-decoration: underline; }
  .lucida { font-family: "Lucida Console", Monaco, monospace; }
  .no-underline { text-decoration: none; }
</style>

<p>
  In JavaScript the 
  <code class="code-underline lucida" id="mycode">alert()</code> 
  method displays an alert box.
</p>

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

<script>
  let toggle = () => {
    let element = document.getElementById("mycode");
    element.classList.toggle("no-underline");
  }
</script>

Code explanation

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

The class attribute in <code> assigns two of those classnames.

Repeatedly clicking the button toggles another class, turning the underline on and off.
