title: What does :global (colon global) do?
body: <p>In some SCSS files, I see the following:</p>
  
  <pre><code>:global {
    /* ... */
  }
  </code></pre>
  
  <p>I don't know if it is an SCSS feature or a CSS feature.
  I tried searching about it but couldn't find any good results at first sight.</p>
