Many sites and online services, like Google Maps, suggest HTML code (usually iframes) to embed widgets and content on your page.
You can add such HTML widgets in your quizzes.
Please note:
In case pasted code is not just iframe tag it will be wrapped into HTTPS iframe.
Only HTTPS sources for iframes, styles and javascript links are supported.
Non-HTTPS sources will be blocked by the browser and won't behave properly.
