HTML <kbd> class Attribute

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

Example

#

A class attribute styling <kbd> elements.

CTRL + C is used to copy content.
CTRL + X is used to cut content.
CTRL + V is used to paste content.

<style>
 .kbd {padding: 2px 4px;color: white;
       background-color: teal;border-radius: 3px;}
</style>

<p>
  <kbd class="kbd">CTRL + C</kbd> is used to copy content.<br />
  <kbd class="kbd">CTRL + X</kbd> is used to cut content.<br />
  <kbd class="kbd">CTRL + V</kbd> is used to paste content.
</p>

Using class

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

Multiple classnames are separated by a space.

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

CTRL + X is used to cut content.

 .teal-bg {padding: 2px 4px;color: white;
           background-color: teal;border-radius: 3px;}
 .indigo-bg {background-color: #4238ca;}
</style>

<p>
  <kbd id="mykbd" class="teal-bg">CTRL + X</kbd> is used to cut content.
</p>

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

<script>
  let toggle = () => {
    let element = document.getElementById("mykbd");
    element.classList.toggle("indigo-bg");
  }
</script>

Code explanation

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

The class attribute in <kbd> assigns two of those.

Repeatedly clicking the button toggles another class, changing the background and text color of the element.
