How to get your custom framed webpage to NOT have the scroll bars....
instead of using Add New Link, use Create Custom Page
enter this code in the HTML area of your webpage, replace the URL, and change with the height/width if you need to. This size should work for most though.
<iframe width="1111" height="1485" style="border:0px;" src="//yourwebsite.com"></iframe>
...just replace the //yourwebsite.com part of it with your own link...Don't replace the quotes! you need them for the code to work.
USING CREATE CUSTOM PAGE (tweak the width/height to suit the website, no more annoying scroll bars)
