Selectors cannot select based on CSS property values, as opposed to
DOM attribute values. So what you write here won't work. It's setting
the width CSS property, not the width attribute in the DOM, but the
other selectors are reading from the DOM.
I think that in general there will never be a CSS selector that
depends on the value of CSS property, because then style resolution
could cause an infinite loop.
