Codelab: A Three-File Tabs App
Step out of the platform and build a real multi-file project: index.html, styles.css, and app.js. Ship a working tabbed settings page with proper file separation.
Step 1 of 5
Set up your project folder
You will build a three-file project — HTML, CSS, and JavaScript living in separate files. This mirrors how real codebases are organised, and it forces you to wire them together with <link> and <script src>.
