问题 I've got this test page going on: http://joshuacody.net/qworky/ Warning: Tons of CSS3. This will only look right in Safari or Chrome. Firefox will be tolerable. All else will be lost. Essentially, when I hover on someone's name, I'd like it to trigger the hover state on their image as well. It's working now, but I feel the solution is inelegant. I'd rather not add more classes.

问题 I am afraid there are similar questions to this but I didn’t found a concrete solution, so I created a fiddle: http://jsfiddle.net/Garavani/yrnjaf69/2/ <div class= "category_item"> <div class= "cat_button"> <span class="title_cat">TEXT</span> </div> </div> CSS: .category_item { position: absolute; background-color: #999; top: 100px; left: 50px; width: 200px; height: 200px; /* seems to be overwriten by animation keyframes */ -webkit-transition: -webkit-transform 0.215s ease-in-out; transition:

问题 I'm trying to get an item that is a pseudo element to change when the parent is hovered over. The pseudo element here is .child:after. I know this works: .parent:hover .child { background: #FF0000; } But this does not seem to work: .parent:hover .child:after { background: #FF0000; } Any ideas?
