What is it?

CSS Protips is a community-maintained collection of short, practical CSS techniques aimed at developers who want to write cleaner and more reliable stylesheets. Each tip explains a common problem and shows a small code snippet, often with a linked demo.

The tips span a wide range of topics: CSS resets and inheriting box-sizing, centering elements with flexbox and grid, using :not(), :is() and negative nth-child selectors, sizing with rem, em and viewport units, and keeping layouts stable with aspect-ratio. Some entries also cover accessibility concerns such as focus styles and the caveats of CSS-generated content.

The project is organized as a Markdown document with a table of contents, and it has been translated into many languages. It is best suited as a reference for front-end developers who already know the basics and want quick, idiomatic patterns.
