A couple of weeks ago I attended Ana‘s presentation on CSS at SmartWebConf. I was amazed by what you can do with only one div and lots of CSS. This was just what I needed to start diving in CSS3. I started by opening an account on codepen (really useful tool) and in about 25-30 minutes I managed to create a “pixel-art” Mario. For this I used 160 box-shadow values and only one div. More than that, Mario is resizable thanks to LESS.
You can see the code here and can use it in your projects. Don’t forget to link me.
