## What it is
LessHat is a library of smart LESS CSS mixins that generate cross-browser CSS3 properties with vendor prefixes. It provides mixins named after standard CSS3 properties, including support for keyframes, gradients, and shadows.

## Use cases
- generate cross-browser CSS3 with vendor prefixes in LESS
- use mixins for border-radius, gradients, and shadows
- write keyframes animations in LESS
- use mixins alongside Bootstrap stylesheets
- avoid hand-writing vendor-prefixed CSS

## When to choose
- your project uses LESS and needs CSS3 cross-browser mixins
- you want standard CSS property names for your mixins
- you need Bootstrap-compatible prefixed mixins

## When to avoid
- your project uses Sass instead of LESS
- you target modern browsers only and don't need vendor prefixes
- you need an actively developed library (last release 2022, core from 2016)
