    A Chrome extension that extracts used CSS and combines it into one file▲40

    just wanted to share this useful tool with you. I have been looking at something like this for a very long time. https://chrome.google.com/webstore/detail/css-used/cdopjfddj... what it does: it analyses your html dom and looks for css classes. Then it extracts it all and combines it into 1 single css file. I used 5 css framworks which was on 340kb kb. This tool made it 36kb!

    My 24-hour project, instacss.com▲90

    http://instacss.com (in case DNS update hasn't propagated: http://morning-warrior-3377.herokuapp.com/) Last night I was annoyed at how slow (and web 1.0-ish) most CSS reference sites seem to be, so I created this. It's basically a scrape of the CSS reference on w3schools, but with client side searching. Feedback is most welcome! some of the tech involved: node, requirejs, backbone, mongodb the code: http://github.com/rgarcia/instacss
