## What it is
LostGrid is a PostCSS plugin that provides a fraction-based CSS grid system using calc(). It works with any preprocessor or vanilla CSS and supports float and flexbox modes.

## Use cases
- create fraction-based column grids in CSS
- build responsive layouts with a PostCSS grid plugin
- center page containers with max-width and auto margins
- make offset, nesting, and waffle/masonry-style grids
- use a grid system without being tied to a specific preprocessor

## When to choose
- you already use PostCSS and want a lightweight grid system
- you need grid utilities that work with vanilla CSS or any preprocessor
- you want fraction-based columns without heavy configuration
- you need to support older browsers down to IE9/IE10

## When to avoid
- you want modern CSS Grid layout instead of float/flexbox hacks
- your project does not use a PostCSS build pipeline
- you need actively developed features - the project is in maintenance mode
- you need CSS grid features like named areas or auto-placement
