I’m sorry, but I am really struggling to understand how your last screenshot relates to the first one you posted.
Did the problem on your Client homepage go away after disabling your Custom CSS?
Regarding the blue footer that seems to be really tall, in reality it is not. I designed the background color of the entire page (the <html> tag) to be the same color as the footer.
To illustrate, if you add the following to your Custom CSS…
html {
background: initial;
`}
…you’ll see that the footer is actually only 80px tall.
So I really doubt your problem is with the footer. But I honestly don’t understand what your problem is.
