How do I select an element only when inside another element?

Question

I have a question regarding CSS selectors. How do I select a <div> with a specific class name only when its inside a <ul> with a class name saft? This CSS class is used elsewhere and I don't want to change the styling everywhere.

<div id="floater">     <ul class="saft">         <li><div class="textSlide"></li>     </ul> </div> 

Answer 1

Simply use the CSS descendant selector (a space) between the parent element and the descendant element:

ul.saft div.textSlide {     /* CSS rules */ } 

JS Fiddle demo.

In this case the rules applied to the div of class textSlide will only apply if its ancestor is a ul of the class saft. You could, instead, use the immediate child combinator, the > but then you'd have to specify the div in relation to each parent/ancestor up to the one whose class is required, which gives potentially difficult to maintain CSS (not in this case, but it can, over time, become problematic).

Answer 2

Just do:

ul.saft .textSlide {

This achieves what you need
