Do CSS functions exist?

Question

I\'m not sure what to call this, but basically let\'s say I have a style that I use a lot,

.somepattern{
    font-size:16px;
    font-weight:bold;
    borde         


        

Answer 1

I know I'm late to the party but the selected answer IS NOT the right answer since it's deferring it to CSS preprocessors.

To answer the specific question "Do CSS functions exist?", the answer is: Yes.

However, CSS functions work completely different than the OP's concept initially is.

cuixiping's answer seems the most correct answer.

Examples of CSS functions are:

• url()
• attr()
• calc()
• rotate()
• scale()
• linear-gradient()
• sepia()
• grayscale()
• translate()
