White space at the bottom of all pages when zoomed out?

Site URL: https://www.tasklondon.co.uk

Hi,

My website name is tasklondon.co.uk (password:12345). On every page, if I zoom out in the browser, there is a huge amount of whitespace at the bottom of the page.. How do I prevent this? Shouldn't this already be dealt with by the software? This also just happens with some resolutions.

Thanks.

Hi, any help please?

Can you take screenshot the white space? I see fine here.
