Joomla - YouTube Videos Too Big After Gavick Template Update

PROBLEM
After updating my Joomla Gavick template to the latest version, the embedded YouTube videos appeared massively large on desktop browsers.  Mobile browsers looked OK.

SOLUTION
The problem is caused by the fitvids library introduced in later template versions.

- Find the file fitvids.jquery.js in the template's js folder.
- Comment-out line 25 in fitvids.jquery.js.

// var css = '.fluid-width-video-wrapper{width:100%;position:relative;padding:0;}.fluid-width-video-wrapper iframe,.fluid-width-video-wrapper object,.fluid-width-video-wrapper embed {position:absolute;top:0;left:0;width:100%;height:100%;}';
