how to interact with an embedded card?

[James Dunn]

I'd like to embed an OPEN card in another site, so I can reply to comments and basically do everything I can do in an open card on trello.com on another site. How?

Hi, James! Welcome to the Atlassian Community!

The embed feature won't work for fully utilizing Trello's features outside of it, so mainly, you can see the card back in its current state, but if you click to open that card, it'll redirect you to the Trello board it's currently on. 

If you want to test that, you could check our articles on Embedding Cards and Embedding Board Tiles.
I'll also post some instructions in case you're tinkering with embed for the first time. Using the sandbox site https://jsfiddle.net/:

1. Go to a Card on your Trello board;

2. Click on Share;

3. Copy the Embed Code;

4. Past on the JSFiddle website under the HTML section;

5. Click “Run” on the top left.
