Can you nest html forms?

Question

Is it possible to nest html forms like this

so

Answer 1

Use empty form tag before your nested form

Tested and Worked on Firefox, Chrome

Not Tested on I.E.

EDIT by @adusza: As the commenters pointed out, the above code does not result in nested forms. However, if you add div elements like below, you will have subForm inside mainForm, and the first blank form will be removed.
