Now, look at the footer when the site is open in a narrow window:

You see, that the links Sitemap, About Us, Contact Us, ... are missing, also the social network icons are grey in the narrow view vs. colored in the wide view, and also the copyright line is gray in the narrow screen, while wide in the wide screen.

All this should be fixed in the narrow-screen view to be consistent with the wide-screen view, to look like this (sure, the spacings between the elements should be nice and equal, excuse my poor drawing skills):

This issue should be fixed both in this repo, and in the https://github.com/appirio-tech/tc-site
I believe, this is a purely CSS fix, as the relevant links are present in the HTML markup, just not shown in the narrow-size window
