The class Attribute

An HTML element's class names can be specified using the class attribute. JavaScript and CSS can both utilize classes to do particular actions on subsets of components and to style elements selectively.

Key Points:

  • Many Uses: An element can be the target of more than one class, delimited by spaces, that can be used with JavaScript or CSS.
  • Reusable: A valuable tool for implementing consistent style or actions, the same class can be applied to several items.

Example:

<div class="header highlight">
    <p class="highlight">This text can be styled distinctly.</p>
</div>

You might style these classes with CSS like this:

.highlight {
    background-color: yellow;
}
.header {
    font-size: 24px;
}
