Am I just missing a variable equivalent?

G'day guys and @mikke89 , first of all thank you for your work.

What I am looking for is some way of getting the behaviour similar to css variables or class inclusions. I want to set some class in a global style and then be able to call that in a template that is importing it. So here's a very basic example, and its just pseudo so don't sweat the syntax, you should get the point.

// styles.rcss

.text-dark {
   color: rgb(50, 50, 50);
}
// or 
--dark-text-color: rgb(50, 50, 50);

and then in my template

// widget.rml
rml
   head
       link ref="styles.rcss" /
       style
          .hoverable-text:hover{
             @include .text-dark
          }
          // or
          .hoverable-text:hover{
             color: var(--dark-text-color);
          }
       /style
   /head
   body
      div
         p class="hoverable-text"
            hover me
         /p
      /div
   /body
/rml

is this a solved problem? Of course I could set that value in both places but then I would have no need for variables and to update it would require updating it everywhere.
My want is born of a theming requirement in that I want to set a pallet's properties once and then call them everywhere.

css variables are not supported in rmlui, see #517. There is a pull request #388 that didn't got merged due to performance issues, but it is fully functional (afaik) and you can merge it yourself locally

Thank you for this, its a gosh darn shame. It would be SUCH a powerful feature.
