Cancel a CSS declaration

Question

Is it possible to have a CSS rule which basically \"undoes\" a prior rule?

An example:

    some text more text ot         


        

Answer 1

Ok, the additional text with example clarifies the question a lot. And I'm affraid that what you want is not possible.

If you know the "unknown colour" you can of course repeat the color. But I think CSS needs some mechanism to add variables or references.

So you have to stick to the cumbersome:

ul {
  color: blue;
}
li ul {
  color: sameenvironment;  /* Sorry but you have to add the specific colour here */
}
