mailto potential - what can i do with it?

Is it possible to embed html in a message body generated by a mailto link? And/or embed pictures or JavaScript as well? If yes,开发者_如何转开发 can you provide an example (it doesn't need to be encoded)?

Also, which other things can I do and which important things can't I do?

Yes, you can!

You can post a lot in the body, you just have to escape tags with html entities, like > < ". And I believe there is a URL length limit.

Oh, and don't forget to urlencode at the end!
