 You're covered! If you don't want your users to download a large CSS file, replace the `<link>` tag with a `<script>` tag:
 
 ```html
-<script src="https://cdn.rawgit.com/marmelab/universal.css/master/universalCssGenerator.js" />
+<script src="https://cdn.rawgit.com/marmelab/universal.css/master/universalCssGenerator.js"></script>
 ```
 
 That's right! Our generator works both in the backend and in the frontend - it is truly universal. The JavaScript file is much lighter, and will load very quickly. Once loaded, it generates the universal.css styles directly in the browser.
