Hi everybody.
I hope this proposal can be technically achievable.
Pseudo selectors and attribute selectors are useful in defining
uniformities for elements which go beyond those defined with tag name,
class and descendants, but there are cases when it would be useful to
define properties as if the elements belonged to the same class.... but
they don't. Designers can't always order changes to class definition in
elements (or this can be undesirable for any reason).
Custom classes, or custom property blocks, could easily solve these
I also add that programmable stylesheet languages such as LESS allow
authors to nest entire blocks of properties along with their selectors.
That is undesirable, but I don't think there would be any issue in defining
zero-specificity blocks to be "copied" where needed.
Has there been any similar proposal in the past?
