A plugin for Fresh that allows you to use Emotion for styling. Doesn't use @emotion/react but @emotion/css instead.

1. In your main.ts, import the plugin:

   import { emotionPlugin } from "https://deno.land/x/fresh_emotion/mod.ts";
   
   // Then use it with Fresh.
   await start(manifest, {
     plugins: [
       emotionPlugin(),
     ],
   });

2. In a Component, e.g. components/MyComponent.tsx:

   import { css, cx } from "https://deno.land/x/fresh_emotion/mod.ts";
   
   export function MyComponent() {
     return (
       <div
         className={cx(
           css({
             color: "yellow",
             backgroundColor: "hotpink",
           }),
         )}
       >
         <p>CSS-in-Fresh!</p>
       </div>
     );
   }
