Footer does not move correctly

[rushsteve1]

Describe the bug
When the page is full height the footer does not move down properly. It can often end up on top of other elements blocking them.

To Reproduce
Steps to reproduce the behavior:

1. Go to /signup or other pages
2. Fill out the form
3. Attempt to click the button
4. Cannot click it since the footer is in the way

Expected behavior
The footer should be pushed down lower and remain out of the way. I believe the footer is not being pushed off the screen when it should be.

Screenshots
If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

• OS: All
• Browser: Chrome, partly Firefox

Additional context
This is a more severe problem on low-resolutiond devices or when the page is zoomed in.
