Using class

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

Multiple classnames are separated by a space.

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

Code explanation

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

The class attribute assigns one classname to the <hr> element.

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