Based on the awesome HTML5 boilerplate, this repo includes typical changes and additions that I usually make. One main differene is that third-party files (aside from HTML5 Boilerplate itself) is treated as Bower dependency.
Yes, I suppose you could use this for static HTML, but how often does that happen anymore? Regardless this can be the starting point for your _layout.mustache, _layout.twig, _layout.nunjucks, _layout.html, _layout.... ok you get the picture.
You should be using LESS, so this will hopefully encourage you. I have compiled the main.less into a main.css so you can get up and running if you don't use LESS, but really you should (or SASS, but these files are LESS specific).
I've decided to include them in the repo in the event that the user might not be familiar with using Bower. I had no idea about how to use it not too long ago, and figure a lot of people might be in that situation. Besides, I want this to be a clone-and-go resource.
