Problems with fixed vertical sidebar

I used the fixed vertical sidebar template to create a landing page. I shifted the sidebar across to the right.

When I try and hide the sidebar across different viewports (tablet and smartphone), I’m left with a space where the right hand content side won’t meet the edge of the viewport.

I added all the left hand col content in sections so I’m a bit lost. I’ve noticed another site using webflow achieved something similar - http://bookinghero.co/

Can someone let me know how I can achieve the same result as booking hero?

Hey @grandtheftpixel can you post your troubleshooting link so we can fiddle around and see why there’s a gap?
