[Selectors4] Another interpretation of [att~=val] when val contains space from Kang-Hao (Kenny) Lu on 2011-03-11 (www-style@w3.org from March 2011) (original) (raw)

(On courtesy of John Hax's proposal[1])

I think this should have been proposed before, but I'll post it again in case it hasn't.

Currently, for [att~=val], the selectors spec says:

[[ If "val" contains whitespace, it will never represent anything (since the words are separated by spaces). ]]

I am wondering whether we can redefine this to be a list of possible match. Namely,

[rel~="a b c d"]

should represent what is represented by

:any([rel=a],[rel=b],[rel=c],[rel=d])

The use case is something like,

nav a[rel~="prev next first last up"]::before { border-radius: 4px; background: url(nav-link-bg.png) } which will be less lengthy than the :any equivalent.

My personally opinion is that the use case is not strong enough to add a hack to the current syntax, but I am curious about what folks in this forum think.
