CSS3 Transition Ease in and out Box Shadow

Question

I am trying to get div id to ease in and out of a box shadow using CSS3.

The current CSS I have is:

#how-to-content-wrap-first:hover {
    -moz-box-shadow: 0px 0px 5px #1e1e1e; 
    -webkit-box-shadow: 0px 0px 5px #1e1e1e; 
    box-shadow: 0px 0px 5px #1e1e1e;
    -webkit-transition: box-shadow 0.3s ease-in-out 0s;
    -moz-transition: box-shadow 0.3s ease-in-out 0s;
    -o-transition: box-shadow 0.3s ease-in-out 0s;
    -ms-transition: box-shadow 0.3s ease-in-out 0s;
    transition: box-shadow 0.3s ease-in-out 0s;
}

The issue I am having is that on the first hover of the element there is no easing in or out and then any subsequent hovers ease in but do not ease out.

Any advice people have would be much appreciated?

Answer 1

You need to use transitions on .class and not .class:hover

div {
  height: 200px;
  width: 200px;
  box-shadow: 0;
  transition: box-shadow 1s;
  border: 1px solid #eee;
}

div:hover {
  box-shadow: 0 0 3px #515151;
  ;
}

<div></div>
