Specs
-----
1. Must max max height to prevent off screen problems
2. Must be usable on mobile and desktop
3. Must be sticky and always visible (at least desktop)
4. Must set width or leave to grid system
Solution
--------
1. max-height calc on insert/repaint
1. overflow: scroll
2. on mobile/sm/md/lg we can put in little box to side of doc meta
and then set to fixed height based on screen size
2. on xl we can put into sidebar
3. sticky on xl desktop is fine as sidebar uses fixed position
and content has max-height with overflow
3. sticky on col/sm/md/lg is not available
Notes
-----
We could go with container-fluid and use full width of screen.
This would work on all devices and take more space on
$(window).width() needs to be 1800 or more for sticky sidebar...
$("#nav-bar").height()
$(window).height() - $("#nav-bar").height() - 100
Two choices:
if width >= 1800 then sidebar sticky outside container
if widht < 1800 then switch to container-fluid?
...but what about height?
...put next to doc--meta
