Introducing FitVids.js

Introducing FitVids.js

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.

How Do I Use It?

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>
    // Target your .container, .wrapper, .post, etc.

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.

Add Your Own Video Vendor

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^=''], iframe[src^='']"});
  // 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.

Known issues

  • Vimeo Autoplay API is not compatible with FitVids in IE11. You must manually wrap videos you want to autoplay.
