Building a Pure HTML5 and JavaScript Icons Editor

I've just released my first web based project. It's a pure HTML5 and JavaScript icons editor which I thought, coming from a Windows background, would be a good way for me to learn some of the capabilities and limitations of these technologies. So with that in mind, I decided I would not allow myself any server side code and once the initial page had been loaded every feature had to be implemented without any further calls back to the server.

Building a Colour Picker With HTML5, JavaScript and JQuery

I have recently been teaching myself HTML5 and JavaScript and had an idea for a project in which I would need to use a colour picker. After a little research I soon discovered the new HTML5 input types, one of which is a colour picker. Great! One problem though, although it does work very well in Chrome, it is not supported in Firefox 22 or IE10.
