Professionnel HTML Aperçu
Fonctionnalités
- Live preview pane for pasted HTML in a sandboxed iframe
- iframe sandbox has no permissions — scripts, forms, popups, and top-navigation are all blocked
- CSS and HTML structure render normally; <script> tags are inert
- Useful for testing snippets and viewing copy-pasted output
- For a runnable HTML environment with JS, use CodePen / JSFiddle / StackBlitz
Mode d'emploi
- Entrez votre entrée données dans le provided field.
- Configure tout options as needed.
- Voir le résultats instantanément et copy ou download le sortie.
Conseils et bonnes pratiques
- Sandbox is empty by design — pasted markup cannot execute JavaScript in this origin. This protects you from accidentally running hostile code.
- CSS and HTML render exactly as the iframe sees them, including responsive media queries.
- External resources (<link href="https://...">) are fetched normally — the browser shows mixed-content warnings if you mix HTTPS and HTTP.
- Inline event handlers (onclick="…") are present in the DOM but don't fire because scripting is disabled.
- For interactive testing where you want JS to run, use a code-editor environment with a sandbox you control.
