Hello. I'm a super-lightweight theme called Susty. I have been built to demonstrate how small a WordPress site can be (just 6KB of data transfer, or 7 with Yoast!).
Note: I am an experiment in minimalism, which means that the aim of this theme is to provide just enough code to power the interface of Susty WP. It is therefore not recommended that you just go ahead and activate for your production blog or website without making some adjustments first.
The goals of this theme are outlined in a blog post entitled, Delivering WordPress in 7KB.
