# @react-pdf/stylesheet > React-pdf styles engine ## How to install ```sh yarn add @react-pdf/stylesheet ``` ## How it works ```js import stylesheet from '@react-pdf/stylesheet'; const container = { width: 400, height: 600, orientation: 'portrait', }; const style = { margin: 20, width: '50vw', height: '20vh', borderRadius: 5, fontWeight: 'semibold', borderBottom: '2 solid yellow', '@media max-width: 500': { backgroundColor: 'rgb(255, 0, 0)', }, }; const computed = stylesheet(container, style); // Computed // { // width: 200, // height: 120, // marginTop: 20, // marginLeft: 20, // marginRight: 20, // marginBottom: 20, // marginBottom: 20, // borderTopLeftRadius: 5, // borderTopRightRadius: 5, // borderBottomLeftRadius: 5, // borderBottomRightRadius: 5, // fontWeight: 600, // borderBottomWidth: 2, // borderBottomStyle: 'solid', // borderBottomColor: 'yellow', // backgroundColor: '#FF0000' // } ``` This library exports a `stylesheet` function that takes two arguments: - _container_: Container where the styles are being computed into. It specifies the `width` and `height` in points (needed for media queries and unit conversions), and optionally the container `orientation` (needed for certain media queries). - _style_: Style to be computed. JS object with raw styles that you would like to get in a normalized format. ## License MIT © [Diego Muracciole](http://github.com/diegomura)
