Steamblr: a Tumblr theme based on steampowered.com
In a little project that grew way out of hand, I ended up making a full-fledged Tumblr theme! I'm too lazy to take screenshots, so you can just see it live here. In order to make a blog about amusing scam attempts on Steam, I stole lovingly borrowed code from Steam's website to make a theme that looks very similar to it. The theme is still a bit goofy in a few aspects and there's still some stuff I want to add to it, but I'm pretty happy with how it looks at the moment.
To install it, go to Blog Settings and hit Customize. Hit "Edit HTML", erase everything (maybe back it up to a text file?) and replace it with everything in this file. Hit "Update Preview", then "Save", then refresh the page. There are plenty of options to adjust, and I wrote a guide thingy here for it. It can now be installed directly from Tumblr's theme gallery.
Anyway, hope you like it! I'd love to hear from you if you decide to use it :D. I'll probably make an update at some point, so you might wanna follow me or track the "steamblr" tag if you use it.
