How Can I Reuse CSS Rules Without Directly Referencing Them?

Referencing CSS Rules: Demystifying the Art of Rule Reuse

While CSS embraces code reusability, the ability to directly reference one rule-set within another remains elusive. However, there are alternative ways to achieve a similar effect and maintain code efficiency.

In the example provided:

<div class="someDiv"></div>

.opacity { filter: ... }
.radius { ... }

we encounter the challenge of applying both opacity and radius styles to the someDiv element.

Instead of referencing rules, you can reuse selectors on multiple rule-sets:

.opacity, .someDiv { ... }
.radius, .someDiv { ... }

This approach applies both sets of rules to the someDiv element.

Alternatively, you can use multiple selectors on a single rule-set:

.opacity.radius { ... }

This approach requires adding multiple classes to the HTML element:

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

To enhance code clarity, it's recommended to use class names that describe the purpose rather than the appearance of elements. Keep the styling details within the CSS stylesheet to separate concerns and maintain flexibility.
