Attributes for <FRAME ...>
MARGINWIDTH =size in pixels
MARGINHEIGHT =size in pixels

MARGINWIDTH and MARGINHEIGHT control the inside margins of the document in the frame.

this code	produces this
<FRAMESET ROWS="60%,*,*"> <FRAME SRC="mwTop.html"> <FRAME SRC="mwMiddle.html" MARGINWIDTH=1> <FRAME SRC="mwBottom.html" MARGINWIDTH=50> <NOFRAMES>NOFRAMES stuff </NOFRAMES> </FRAMESET>	this page
<FRAMESET COLS="33%,33%,*"> <FRAME SRC="mhLeft.html"> <FRAME SRC="mhCenter.html" MARGINHEIGHT=1> <FRAME SRC="mhRight.html" MARGINHEIGHT=50> <NOFRAMES>NOFRAMES stuff </NOFRAMES> </FRAMESET>	this page

The official specifications say that MARGINWIDTH and MARGINHEIGHT should be set to values of greater than 1... 0 is not an acceptable value. Some browsers will honor margin settings of 0, while others don't.

Both Netscape and MSIE display some odd behavior with these attributes: the default for MARGINWIDTH (i.e. if you don't use it) is around 13 or 14 pixels. However, if you use MARGINWIDTH, then the default for MARGINHEIGHT changes to 1. The reverse is also true. Take a look at the pages in the examples above to see this strange behavior.
