Search for unused CSS in all files

[BobTorgerson]

An example of code that has CSS that is unused is in the footer:

Line 15 and 16 in the footer looks like this:

<div class="**colored d-none d-xl-block**">
    <div class="logo-block **container-fluid** footer-container">

The CSS classes marked in bold are not used and have no purpose being in the code.

I've gone through and done a search for unused CSS while doing development on other areas of the code. I'll keep it open to remind us to look for dead end CSS classes.
