In Chrome, click in the results pane and hit tab to focus on the first link here:
http://jsfiddle.net/2q6c7c36/2/
notice how the contents of .box "jump up" outside of its border? It appears to be caused by the clearfix class I'm using. Is this a bug in Chrome or something I'm doing wrong? I've noticed it when using pseudo elements for icon fonts as well.
Thanks.
.clearfix:after{
content: ".";
visibility: hidden;
display: block;
height: 0;
clear: both;
}
