The “class” attribute in HTML is used to assign one or more class names to an element, allowing developers to apply styling or behavior to multiple elements with a single identifier. Unlike the “id” attribute, which must be unique within the document, the “class” attribute can be used to group elements that share similar characteristics or functionality.
Syntax
<tagname class="classname1 classname2 ...">Content</tagname>
