Problems customizing HTML exporter

Hi guys, I´m trying to put a border on my html5 exported games. So I got to C:\Program Files\Construct 2\exporters\html5\templates and changed the style to

	<style type="text/css">
		#c2canvasdiv 
		{
			border:thick;
			border-style:ridge;
		}
	</style>
[/code:3g0unfp5]
if I put this code in the index.html it works, but I dont want to do that every time I export, so I changed export.html directly, but it seams tha C2 override this file every time, so where can I put a default CSS code to my exported games ?

I didn't try this out yet but I think it could be possible using the CSSimport plugin.
