CSS selector based on a condition

Question

I am trying to get a CSS selector to check and apply the CSS based on the condition that if: sectionContent-noToolbar is available, then apply height:2em

Answer 1

CSS can't help you. You can achieve this with javascript since it can traverse in DOM. jQuery is quite neat for this task. Just select the node you want using css selectors and traversal functions like parents, siblings or children` and modify the found elements' style manually.
