You'll find a new link under Resources section for our course: CodePen. You may remember we looked at some CSS/JavaScript samples on CodePen a couple of weeks ago -- it is a good place to showcase one's work. But also, it is a good place to actually DO your work: you type in your HTML/CSS/JavaScript in one box and right below your see what it looks like or what it does, without having to switch to another window. It is also a place where you can find elements that you can reuse in your sites, so all around a great resource for a front-end developer.
