[TypeStyle] Use fallback values in TypeStyle for better browser support

You can increase the browser support of your CSS using fallback values and vendor prefixes. This lesson covers using vendor prefixes and fallback values (single prop multiple values) with TypeStyle. It also shows best practices for maintaining variables in the presence of vendor prefixing.

import { style, cssRaw, types } from "typestyle";

import * as React from "react";

import * as ReactDOM from "react-dom";

cssRaw(`

    body {

        font-size: 1.5em;

        font-weight: bold;

        color: gold

    }

`);

const scroll: types.NestedCSSProperties = {

  "-webkit-overflow-scrolling": "touch",

  overflow: "auto"

};

const bg = style(scroll, {

  backgroundColor: [

    /* The fallback */

    "rgb(200, 54, 54)",

    /** Graceful upgrade */

    "rgba(200, 54, 54, 0.5)"

  ]

});

const App = () =>

  <div className={bg}>

    Hello World!

  </div>;

ReactDOM.render(<App />, document.getElementById("root"));
