I have switched to Montezuma for its responsive design. I really like it a lot. I have one strange issue which I cant resolve through inspecting elements:

When the mobile site is activated (by phone or decreasing browser screen) a strange margin is activated on the right side of my site. I have tried to see which css is causing this but I cant find it.

site: www.bartvandermark.nl

See below for some screenshots:

what browser are you using?
Do you see the same thing in other browsers?
Which did you test?

I tested in Chrome desktop logged in, IE9 not logged in and Chrome for android on android phone. All showed the strange margin on the right when mobile site (with menu) activated.

I cannot find which css is causing this, can you?

Do you get the same results if you uncheck "Show Toolbar when viewing site" in your user settings? This is just a thought as that has caused some "issues" for me in the past.

Turning off toolbar did the trick for the pc browsers. On my phone I still have the margin on the right side: that's is just the most annoying one...

So is there a margin on BOTH sides?
