Use CSS transitions to link Media Queries and JavaScript – Paul Hayes
A common problem in responsive design is the linking of CSS3’s media queries and JavaScript. For instance on a larger screen we can restyle, but it might be useful to use JavaScript and pull in different content at the same time, e.g. higher quality images. With CSS transitions, specifically their transitionEnd events, we can marry up our media queries and JavaScript perfectly, without resorting to window resize events.
