How can CSS incorporate the color of a different class?

Question

How can CSS incorporate the color of a different class?

Is it feasible to reference a color from one CSS class to another? Or generate a universal color definition that can be applied to multiple classes, eliminating the need to update in various places when changing a color?

For instance, if I have a CSS class intended for certain elements but wish to utilize the same color as the Bootstrap "danger" class, is there a method to achieve this? Or must I manually extract the color value from the Bootstrap CSS file and incorporate it into my custom class?

Answer №1

If you're looking to customize colors in Bootstrap 4, consider using the new CSS variables. This feature allows you to override colors without the need for compiling CSS files again.

With CSS variables, you get the flexibility similar to Sass's variables but with the advantage of being served directly to the browser without prior compilation.

Here is an example:

.text-teal {
  color: var(--teal);
}

If you want to set a global color using the ::root selector, you can follow this example:

:root{
     --blue-shade:#ae1234;
}

Then, you can easily use this color anywhere in your CSS by simply calling it with var() function like so:

.box{
    border: 2px solid var(--blue-shade);
}

.text{
   color:var(--blue-shade);
}
