How can I outline a frame so it will look like this...

----------
| blah blah |
| blah blah |
| blah blah |
----------

... or somewhat like that i just weant it bordered with dashes??

For example:

<iframe src="inline.html" name="inlineframe" width="100%" height="100%" frameborder="0" style="border: 1 dashed #800000"></iframe>


Or do you mean normal frames? If so, see thread:
