Global & Third-Party Styles
It is a common technique to start the whole styling process by adding some global styles such as CSS resets.
In addition you might also include some third-party styles. To do so, the renderer provides a method called 
.
It accepts either a valid CSS string or a basic style object with a custom selector to be rendered into.renderStatic
Style Object
If you prefer using style objects, do not forget to provide a selector as well.
Note: Style objects will also be processed with all applied plugins.
import { createRenderer } from 'fela'const renderer = createRenderer()const styleObject = {  fontSize: '12px',  width: '100%',  display: 'flex',}renderer.renderStatic(styleObject, 'html,body,#app')CSS String
Rendering CSS strings is especially helpful if you want to use third-party or legacy styles written in CSS.
This method is not recommended as no further processing with plugins is done. It should only be used to insert large third-party CSS files.
import { createRenderer } from 'fela'const renderer = createRenderer()renderer.renderStatic('*{margin:0;padding:0}')Template Strings
Using ECMAScript 2015 template strings(new tab) we can even write multi-line CSS styles. 
This is helpful if we want to copy large CSS files directly into our JavaScript file.
import { createRenderer } from 'fela'const renderer = createRenderer()renderer.renderStatic(`  * {    margin: 0;    padding: 0  }  body, html {    width: 100%;    height: 100%  }  div {    display: -webkit-flex;    display: -moz-flex;    display: flex  }`)
