Libraries

Here you’ll find a list of libraries, polyfills and other kinds of reusable scripts I’ve developed over the years.

-prefix-free

-prefix-free is a library that allows you to write standard, prefix-less CSS and have the necessary prefixes added on runtime. It uses feature detection for almost everything. In some ways, I consider -prefix-free my best work so far.

Chainvas

Chainvas is a tiny generic chaining library that can make any API’s methods chainable (like jQuery). Official plugins for the DOM and the Canvas API included.

CSSS

My popular slideshow framework, built exclusively with open web technologies. Includes plugins for editable CSS regions, syntax hightlighting and more.

rgba.php

A server-side script that automatically generates semi-transparent PNGs to be used as fallbacks for RGBA colors.

    Hi Lea, I really like the HTML5 progress bar polyfill.  Is there a license for it?  I didn’t see one on github.

    It’s MIT License, as in most my work. Just forgot to add it. I’ll try to remember to add it soon (or you can always send a pull request and save me the hassle :P )
