For my website's sticky footer, I followed this technique:
I wanted to add a border around the entire site that also encompasses the footer, but ran into an issue where it did not extend around the page properly. Here is what happened: https://i.sstatic.net/vmwTT.jpg
You'll notice in the image that the white box does not move down to the footer section.
To illustrate the problem, here is a jsfiddle link: http://jsfiddle.net/hc3Xu/14/
I previously asked a similar question without realizing it was related to the footer. The response mentioned that the issue might be caused by setting height: auto !important; in the container class, which prevented the content container from stretching to 100%. However, removing this causes another issue where the footer no longer sticks to the bottom of the page. I am currently stuck and unsure how to proceed.
