    Good point. @rehevkor5 is it possible to only hide the color boxes when the 
browser window is very narrow?

> When the window is not wide enough, or when the job name is too long, the 
> "Cancel" button in the Job view of the web UI is not visible because it is 
> the first element that gets wrapped down and gets covered by the secondary 
> navbar (the tabs). This causes us to often need to resize the browser wider 
> than our monitor in order to use the cancel button.
> In general, the use of Bootstrap's ".navbar-fixed-top" is problematic if the 
> content may wrap, especially if the content's horizontal width if not known & 
> fixed. The ".navbar-fixed-top" uses fixed positioning, and therefore any 
> unexpected change in height will result in overlap with the rest of the 
> normal-flow content in the page. The Bootstrap docs explain this in their 
> "Overflowing content" callout.
> I am submitting a PR which does not attempt to resolve all issues with the 
> fixed navbar approach, but attempts to improve the situation by using less 
> horizontal space and by altering the layout approach of the Cancel button.
