Why is this needed? How does Views use CSS? Will this affect Mac, etc.?

The supplied updated icon has padding which makes the positioning off on the
chrome://crashes page. This is a fix for that. However as I'm getting new
cropped icons this isn't required. 

   background-repeat: no-repeat;
   font-size: 156%;
   font-weight: bold;
   margin: 0;
   padding-bottom: 20px;
   padding-top: 20px;
 }
