Cascading Style Sheets, or CSS for short, is a style sheet language written in a markup language. CSS defines the presentation, look and formatting elements of Web documents, such as the layout, colors and fonts.
CSS syntax is comprehensive, and it is not easy to always know the exact syntax, or know all the available CSS properties and corresponding values. To help CSS developers and designers, Toptal created a quick reference guide
and offered it to the community as a free download. The CSS reference guide includes CSS syntax, the most important selectors, properties, sizes and units, and other useful CSS information in a short and informative format. We
hope you will find the CSS cheat sheet a valuable resource.
