<h1>Example of CSS effects on a live video stream</h1> | |
Note that we used the <a href="https://github.com/postcss/autoprefixer">autoprefixer.js library</a> that adds automatically and when needed prefixes to the CSS properties.</p> | |
<p> | |
The JavaScript code is in the JavaScript Tab, CSS code in the CSS tab. | |

Click on the video to toggle the different effects.</p> | |
