I recently had fun playing a bit of a prank on a colleague of mine by using Google Docs scripting to update a cell based on its content.
I was sent an article earlier today about logging client side errors on the server, and I had one of those classic "why didn't I think of this before?" moments.
Just a cool little technique I recently used for animating accordion arrows (indicating whether the accordion item is open or closed) using some JS, CSS3 (for displaying and animating) and pseudo selectors.
Having had a thing for cubees, I figured it would be awesome to build a rotating model of one in the browser using three.js
I'm so glad to see this making it's way into native CSS. It's probably still a long way off, but it's always good to know that the WG is taking notice of how pre-processors are taking off!
