How do I apply multiple CSS classes to a single HTML element?

Applying Multiple CSS Classes to a Single Element

It is possible to assign multiple CSS classes to an HTML element. This allows you to apply various styles and behaviors to the same element simultaneously.

Method 1: Using Multiple Class Names

To apply multiple classes to a single element, simply list them in the class attribute, separated by spaces. For instance:

<code class="html"><a class="c1 c2">aa</a></code>

In this example, the anchor tag receives both the c1 and c2 classes.

Method 2: Using CSS Selector

To target elements that contain all of the specified classes, use this CSS selector without any spaces:

<code class="css">.c1.c2 {
  /* Styles */
}</code>

This selector will only match elements that have both c1 and c2 classes applied.

Troubleshooting

If applying both classes simultaneously does not work, ensure that there are no conflicting styles applied to the element. Check your CSS file or browser inspector to confirm that the classes are being applied correctly.
