A lightweight, easy-to-use jQuery plugin for fluid width video embeds.

FitVids automates the Intrinsic Ratio Method by Thierry Koblentz to achieve fluid width videos in your responsive web design.

Include jQuery 1.7+ and FitVids.js in your layout and target your videos container with fitVids().

<script src="path/to/jquery.min.js"></script>
<script src="path/to/jquery.fitvids.js"></script>
<script>
  $(document).ready(function(){
    // Target your .container, .wrapper, .post, etc.
    $("#thing-with-videos").fitVids();
  });
</script>

This will wrap each video in a div.fluid-width-video-wrapper and apply the necessary CSS. After the initial Javascript call, it's all percentage-based CSS magic.

Have a custom video player? We now have a customSelector option where you can add your own specific video vendor selector (mileage may vary depending on vendor and fluidity of player):

  $("#thing-with-videos").fitVids({ customSelector: "iframe[src^='http://mycoolvideosite.com'], iframe[src^='http://myviiids.com']"});
  // Selectors are comma separated, just like CSS

Note: This will be the quickest way to add your own custom vendor as well as test your player's compatibility with FitVids.
