🔐 Safety & Sanitization

To keep you safe, the app cleans your HTML:

  • Disallowed: <script>, <form>, inline JS, and similar.
  • Only certain attributes and tags are allowed (like <img src="">, <a href="">).
  • Video embeds only work from YouTube and Vimeo (via HTTPS).

💾 Auto-Save

The editor automatically saves your progress in the browser (via localStorage). Revisit the app later and your last session will still be there.
