Thanks for this PR! It works for narrow screen sizes. But the space could also be reduced on desktop screen sizes too. The bottom space is still larger than the top space for screen widths larger than 768px. But considering that it's a frequent user complaint that KJS wastes screen space even on desktop, we could perhaps try making these changes universal in the app, rather than only at small screen widths.

The other thing is whether you checked that the !important is actually necessary in all cases. There is an issue from a previous dev suggesting we try to reduce or eliminate the use of !important in our css, though I'm not sure that'll be possible while we're still using this older version of Bootstrap.
