Respond.js: No Comments Necessary
Earlier this year, Filament’s Scott Jehl released Respond.js, a small and fast script that brings CSS3 Media Query support to browsers like Internet Explorer 6-8, allowing you to build cross-browser Responsive Designs. As of last week, Respond.js no longer requires that you add the CSS comments it formerly needed to properly parse the media queries in your CSS — all you need to do is include the script and write CSS as you normally would. Added bonus: it’s 85% faster in IE!
