Andreas Kling 968ad0f8d1 LibWeb: Some improvements to CSS height:auto computation for blocks
Auto block heights are now computed according to something that kinda
resembles the specification.

Blocks with inline children and height:auto have their height computed
based on the top of the first line box and the bottom of the last line
box. Very straightforward.

Blocks with block children and height:auto have their height computed
based on the top of the first in-flow block child's margin box, and the
bottom of the last in-flow block child's margin box.

SerenityOS

Graphical Unix-like operating system for x86 computers.

About

SerenityOS is a love letter to '90s user interfaces with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.

Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix. This is a system by us, for us, based on the things we like.

I (Andreas) regularly post raw hacking sessions and demos on my YouTube channel.

Sometimes I write about the system on my github.io blog.

I'm also on Patreon and GitHub Sponsors if you would like to show some support that way.
