How can I combine CSS styles for multiple classes to reduce code duplication and improve maintenance?

Combining Styles for Multiple CSS Classes

In CSS, it's common to style different elements with unique properties. However, sometimes, you may encounter situations where multiple classes share the same styling rules, leading to code duplication and potential maintenance issues.

Let's consider the following example:

<code class="css">.abc {
  margin-left: 20px;
}

.xyz {
  margin-left: 20px;
}</code>

Both the .abc and .xyz classes set the margin-left property to 20px. This redundancy can be eliminated by combining both classes in a single style declaration:

<code class="css">.abc, .xyz {
  margin-left: 20px;
}</code>

This declaration applies the left margin style to both classes, allowing you to maintain a consistent style without repeating the code. The comma-separated class names within the selector indicate that the rule applies to any element with either the .abc or .xyz class.

By merging similar style declarations, you can optimize your CSS code, reduce maintenance overhead, and improve its readability and reusability.
