What is the reason behind CSS classes being designed to not be able to include another CSS class?

Why is it that one CSS class cannot encompass another CSS class, like this example:

.parentCSS {
  width:100%;
}
.childCSS {
}

I'm running into a lot of redundant code in my files because of this limitation.

At times on the aspx page (where one control has many CSS classes) and at other times in the CSS file (where one CSS class has many duplicate attributes).

If anyone has suggestions on how to write efficient CSS without relying on nesting, I would greatly appreciate it.

Answer №1

CSS was not originally designed to support nesting, but there is a helpful plugin called that allows you to create stylesheets in a more flexible manner.

LESS enhances CSS by adding dynamic features like variables, mixins, operations, and functions. It can be run on both the client-side (Chrome, Safari, Firefox) and server-side, using Node.js and Rhino.

Answer №2

I may not know the exact query, but it is possible in css with the following code:

.container,
.container .item {
    /* styling rules */
}

Answer №3

To apply styles, you must explicitly list all the classes you want to use:

.mainStyle .subStyle { color:red; }
.subStyle { background-color:blue; }

Alternatively, you can group them together in your HTML markup:

<div class="mainStyle subStyle"></div>

It might be beneficial to provide specific details or examples of your desired outcome.
