Basic HTML/CSS Tutorial: Use Image Sprites as Links

In this really horrible 1am tutorial, I will show you a way to make a sprite and use it as a link on your HTML/CSS web pages. If you already have a sprite or image you wanna use skip to 3:30 I made this mostly for homework, but I thought I would upload it just cuz. Also I suck at coding so I hope it isn't totally wrong. I probably won't be able to answer anything other than really basic questions but feel free to start a commenty thing if you are good at coding. PS: Sorry I haven't been uploading SFM stuff, I've been super busy. :c
