Preboot is a collection of LESS mixins and variables for writing CSS, originally the precursor to Bootstrap. It provides lightweight, component-free utilities like color variables, vendor mixins, grid helpers, and utility mixins for LESS-based web projects.

Use cases

• write better CSS with LESS mixins and variables
• jumpstart a web project without a full CSS framework
• get cross-browser vendor prefix mixins for LESS
• use a lightweight alternative to Bootstrap's variables and mixins
• set up a grid system and color scheme in LESS

When to choose

• you use LESS and want lightweight mixins and variables without prebuilt components
• you want a minimal, interface-agnostic starting point for CSS
• you prefer assembling your own stack instead of a full framework like Bootstrap

When to avoid

• you use Sass instead of LESS
• you need prebuilt UI components or a maintained framework
• you need actively maintained tooling - the project has not been updated since 2016
