Do you like
web components?
Have you ever used them before?
Why not?
I just need something quick and easy.

What is a web component?
"Web Components are a set of standards currently being produced by Google engineers as a W3C specification that allow for the creation of reusable widgets or components in web documents and web applications. The intention behind them is to bring component-based software engineering to the World Wide Web. The components model allows for encapsulation and interoperability of individual HTML elements."
tl;dr
Custom HTML elements

<source src="devstories.mp4" type='video/mp4' />
<source src="devstories.webm" type='video/webm' />
