What is the best way to merge several CSS class selectors into a single one?

I am facing an issue with using multiple selector classes in my HTML elements. For example:

  • .rt-grid-6 { ... }
  • .largemargintop { ... }
  • .rt-left { ... }

Currently, I have to use these classes repetitively in my HTML like this:

<div class="rt-grid-6 largemargintop rt-left">
    ...
</div>
<div class="rt-grid-6 largemargintop rt-left">
    ...
</div>
...

This makes it difficult to manage as any change requires updating all occurrences.

I am exploring the possibility of simplifying this by creating a new CSS structure like below:

.item
{
    rt-grid-6; //refer to the mentioned class
    largemargintop;
    rt-left;
}

And then applying it as follows:

<div class="item">
    ...
</div>
<div class="item">
    ...
</div>
...

However, the challenge is that I cannot modify the existing classes directly and still need to utilize their styles. I am unable to redefine styles or access sources as I only receive compiled CSS to work with.

Therefore, I'm seeking a way to enhance maintenance by easily adding or removing classes from a single point without major modifications.

Answer №1

When it's not possible to use less or sass, an alternative approach is to utilize a temporary CSS class name and then replace it using jQuery as shown in the code snippet below:

HTML

<div class="temp-class">aaaaaaaaaaaaaa</div>
<div class="temp-class">bbbbbbbbbbb</div>

JavaScript

$(".temp-class").attr("class", "rt-grid-6 largemargintop rt-left");

See Demo Here

Answer №2

If you're working solely with CSS, it won't be enough. You'll need to utilize a CSS preprocessor like SASS or LESS.

For guidance, check out: http://sass-lang.com/guide

Here's an example using SASS:

.item
{
    @extend .rt-grid-6; //referring to the specified class
    @extend .largemargintop;
    @extend .rt-left;
}

It's that easy!

With SASS, you have access to variables and much more! It's incredibly useful.

Answer №3

Consider utilizing SASS or LESS as a solution for this issue. Your current approach is not effective.
