Re: WebKit now supports CSS Variables

My first idea was to implements constants, too.
But I think that it's good to have an "edit" feature so we can write more 
complex code in the future.

Currently, this is not the main idea to allow CSS! or another thing that can 
have benefits of variables.
But if we'll implements these (of others things we don't have thoug before) 
in the future,
we should implements variables now so we are sure that all is possible in 
the future.

It's also a benefits for JavaScript developers.
