Missing.css 1.0.0-prerelease.1

• Made .fullbleed work in sidebar layouts.

§ Changes in previous pre-release

• Added missing.js, a small collection of JS libraries implementing common UI patterns. Currently contains tabset, menu, and collapsible navbar components.
• Breaking: Replaced .sidebar with .sidebar-layout, which works a bit differently.
• Added .iconbutton.
• Added ARIA listbox and toolbar.
• Added CSS Grid support: .grid and many associated classes to create your layout.
• Added a few missing utilities for setting justify-content, padding, margin.

§ For developers

• The source code of missing.css was completely reorganized! The source files now line up with the pages of the documentation to make it easier to find code.
• Speaking of the docs, they have also received a subtle reorganization.
• The development server will now build changes to the CSS way faster.
