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

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

Using class

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

Multiple classnames are separated by a space.

JavaScript uses classes to access elements by classname.

<li class="classnames">

More Examples

#

A class attribute styling <li> elements. Clicking the button toggles a classname that changes the background color for all items.

  1. Designers
  2. Developers
  3. Managers
Toggle class <style> .job-title { color:teal; padding:3px 0; margin:5px 0; font-style:italic; } .moccasin { background-color:moccasin; } </style> <ol> <li class="job-title ">Designers</li> <li class="job-title ">Developers</li> <li class="job-title ">Managers</li> </ol> <br /> <button onclick="toggle();">Toggle class</button> <script> let toggle = () => { let elements = document.getElementsByClassName("job-title"); [].forEach.call(elements, element => element.classList.toggle("moccasin")); } </script> Try it live

Code explanation

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

Clicking the button retrieves all the <li> elements using the classname.

Javascript then iterates over the elements and toggle another classname changing the list item background color.
