It sounds more like a rock band, but it’s actually a tool for rapid prototyping in html and css, and a fairly easy way for a css-vapid guy like me to give my websites a basic ‘good look’ in about 5 minutes and still have some control over the design. Plus it’s very flexible, they aim to make it so that you can show your website on multiple different devices.
I’ve been playing around with their open-source foundation download code, and I must admit their examples ‘click’ for me. For example to add a button, you specify a css class like this class=”nice blue radius button” which is almost human english ! This way I can focus on my python skills and still produce some nice-looking pages !
