# Introducing FitVids.js
A lightweight, easy-to-use jQuery plugin for fluid width video embeds.
FitVids automates [the Intrinsic Ratio Method by Thierry Koblentz](http://www.alistapart.com/articles/creating-intrinsic-ratios-for-video/) 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()`.
```html
```
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.
## Currently Supported Players
| YouTube | Y |
| Vimeo | Y |
| Blip.tv | Y* |
| Viddler | Y* |
| Kickstarter | Y* |
`*` means native support for these may be deprecated. If your video platform is not currently supported, try adding it via a `customSelector`...
## 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_):
```javascript
$("#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.
## Ignore With Class
Have a video you want FitVids to ignore? You can slap a class of `fitvidsignore` on your object or container and your video will be displayed as it is defined.
If you'd like to add a custom block to ignore FitVids, use the `ignore` option.
```javascript
$("#thing-with-videos").fitVids({ ignore: '.mycooldiv, #myviiid'});
// Selectors are comma separated, just like CSS
```
## Known issues
* Vimeo Autoplay API is not compatible with FitVids in IE11. You must manually wrap videos you want to autoplay.
