This makes me sad. I made a CSS library[1] some time ago and recently could fit the whole landing page into 10kb for the a-k-apart competition[2], which I've reverted ever since to about 15kb in total because there were some sacrifices that I didn't want to make. I'm totally surprised when I see those multi-MB Javascript files.
