You can embed a normal website as an <iframe> by copying the website’s URL, then pasting the URL into a Pitchdeck layer’s Embed input field.

Example Website URL

https://www.newyorker.com/culture/cultural-comment/what-weve-learned-from-dieter-rams-and-what-weve-ignored

Websites that don’t allow cross-origin embeds won’t load. Please note that the website you’re embedding will need to allow other websites to embed it (via a Access-Control-Allow-Origin CORS policy), otherwise the iFrame won’t load and a blank screen will appear instead.
