Hello,
I am brand new to Visualforce and relativily new to Salesforce in general.  I have created a simple Visualforce page that I am inserting into a Lightning Page Layout section.  I can not seem to get the VF page to fill out the width of the page layout section.  

 I know the height is set at the page layout point, I think I have it at 300.

From digging, I am seeing that it can be done via jquery with iframe, but I am not finding a way to actually make it work.  

Can anyone help guide me in the right direction?

thanks,
Travis
