Tried in IE11 (not that one should expect anything to work there, haha) and it looks even more odd (no orange coloring, etc)
This was originally based off of Skeleton, with the intent being how small I could get the source. I looked online for CSS code golf, but I was unable to find any article, or even examples. The only thing I was able to find was CSS shorthand.
This is my code golf experiment. My goal is sub 500 bytes, anything lower probably will not be possible (then again, I said that about sub 700 bytes). My rules are pretty much full feature parity with Skeleton, and looking similar to the way lit looks right now.
The main way I was able to make lit this small was by optimizing for the gzip algorithm. I learned a ton by doing that, including some counter intuitive things when compressing files.
I would love for people to join me and help out, because I am running out of ideas to make the source smaller.
Sometime in the future, when brotli has replaced DEFLATE, lit could be further optimized. In general though, the differences would likely be minimal.
SUB 500 BYTES WOOO
(I would have edited my previous comment, but HN closes comment editing after a while
One of the things that always irritated me about Skeleton was having to type out the number in English. You killed two birds with one stone: I don't have to remember how to spell, and that makes the file size much smaller.
