Check out my new blog post: High performance HTML.
simpl
simpl.info is a website for simplest-possible code examples.
I also maintain a list of resources for working with HTML, CSS and JavaScript.
Your contributions and comments are welcome.
There's a grunt script for creating new examples:
# After clone
$ cd build
$ npm install grunt
$ grunt --feature "new-feature"
$ cd ../new-feature # Go ahead and add what is needed.
