I have just begun getting back into html and CSS with the help of Zaydek's Scrimbla lesson "How to build a blog". It is really helpful and technically only takes 43 minutes, but I spent a lot longer trying to understand the code in a bit more depth and commenting the hell out of it. You can find all of that code and other stuff at my GitHub here.

Also thanks to Mikey for patiently showing me how to cheaply register a domain and host content using AWS. You can find his site here. This post was both a first post, and a way to practice some basic front-end skills.
