 * Would be really nice if your CSS could pass W3C CSS validation.
    Both CSS files:–
   instagram-feed/css/sb-instagram.css – //netdna.bootstrapcdn.com/font-awesome/
   4.2.0/css/font-awesome.min.css have A LOT of elements that don’t pass the validation
   tool.
 * I really like this plugin and would be great this improvement.
 * Thanks a lot in advance.
    Best regards.

 * Hey QROkes,
 * The only validation errors I’m seeing are related to cross-browser fixes and 
   vendor prefixes. Taking these out would cause inconsistency issues across various
   web browsers and wouldn’t be advisable. The plugin has been built to be as cross-
   browser compatible as possible and to work with IE7 and 8, which unfortunately
   means that some outdated CSS declarations need to be included to cater to those
   older browsers. In a perfect world every file would validate 100%, but with the
   number of browsers and the transitional state that CSS is currently in it would
   most likely cause more cross-browser formatting and layout issues than it would
   help.
