HTML <span> class Attribute

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

Using class

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

Multiple classnames are separated by a space.

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

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

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

Code explanation

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

The class attribute in <span> assigns one classname.

Repeatedly clicking the button toggles another class, changing the background color of the <span>.
