How Can I Reuse CSS Styles Without Referencing Rule-Sets?

CSS Rule Referencing

In CSS, it is not possible to reference one rule-set within another. However, there are other methods to achieve similar effects.

Reusing Selectors

You can reuse selectors on multiple rule-sets within a stylesheet. For example:

.opacity, .someDiv {
  ...
}

This applies the same styles to both elements with the opacity and someDiv classes.

Combining Selectors

You can also use multiple selectors on a single rule-set. Separate selectors with commas:

.opacity, .someDiv {
  ...
}

This applies the same styles to elements with either the opacity or someDiv class.

Applying Multiple Classes

Multiple classes can be applied to a single HTML element using the class attribute:

<div class="opacity radius"></div>

This applies the styles defined in the opacity and radius rule-sets to this element.

Best Practices

Consider using class names that describe the purpose of the style rather than specific styling:

.rounded-corners {
  ...
}

Keep the CSS logic separate from the HTML structure to maintain code maintainability.
