I'm trying to create an off canvas mobile menu for a website I'm working on which will replace an old buggy version. I've settled on https://github.com/mobify/pikabu as it does everything I need but I'm having a little trouble with it calculating the wrong height.
You can see the issue at: http://verypc.very-dev.co.uk/
You'll need to shrink the menu down, then hit the 'hamburger' at the top left. The menu slides out but you'll notice that you can still scroll the body of the page. The extra height is coming from pikabu and an inline style that it calculates.
My initial thought is that this is something within my CSS that's possibly causing the extra height but I haven't been able to track it down successfully.
I'm trying to avoid editing Pikabu itself but it's not a huge problem to do so if necessary.
Any help would be great!
