Building Your Own Website? Need CSS layout code?

This certainly isn't for all of you, but for those who are more technologically adept, and you're looking for some free ways to lay out your site, here is a place that has multiple CSS downloads for you to use to format your page(s). This seems like a great place, and the time saved... My question is, does this code work in a place like Weebly? Might be worth a look with your students.
