CSS - style a link based on its “rel” attribute?

Question

 LINK 

is it possible to add css rules for rel=\"external\" ?

Answer 1

Felix Kling and thirtydot suggested to use the [att=val] attribute selector (a[rel="external"]). But this will only work if external is the only rel value.

If you want to style links that could have 1 or more rel values, you should use the [att~=val] attribute selector:

a[rel~="external"] (note the tilde character)

An example for such a link could be:
