# Autoprefixer [PostCSS] plugin to parse CSS and add vendor prefixes to CSS rules using values from [Can I Use]. It is recommended by Google and used in Twitter and Alibaba. Write your CSS rules without vendor prefixes (in fact, forget about them entirely): ```css ::placeholder { color: gray; } .image { width: stretch; } ``` Autoprefixer will use the data based on current browser popularity and property support to apply prefixes for you. You can try the [interactive demo] of Autoprefixer. ```css ::-moz-placeholder { color: gray; } ::placeholder { color: gray; } .image { width: -moz-available; width: -webkit-fill-available; width: stretch; } ``` Twitter account for news and releases: [@autoprefixer]. ---   Autoprefixer is built by Evil Martians, an American design and engineering consultancy for developer tools, AI, and cybersecurity startups. --- [interactive demo]: https://autoprefixer.github.io/ [@autoprefixer]: https://twitter.com/autoprefixer [Can I Use]: https://caniuse.com/ [PostCSS]: https://github.com/postcss/postcss ## Docs Read full docs **[here](https://github.com/postcss/autoprefixer#readme)**.
