variables.scss file and defining css variables in :root and alterting
them based on prefered color scheme. This gives us a mechanism to set
custom color schemes for the entire site from one place and changing
between them just by setting a class to the body element. This is done
by overwriting the css variables and then our scss variables use these
changes and apply them downward. This seems like a really nice setup for
the switching between- and adding color schemes.
Also did a lot of cleanup of unused, duplicate or errors styling
throughout the application.
