I took the initiative to manually download the css and js files for an angular module (here).
In order to make a small adjustment, I modified the css (specifically changing max-width in the media query):
Original:
@media only screen and (max-width: 800px) {...}
Modified:
@media only screen and (max-width: 999px) {...}
However, if I update to the latest version using Bower, my modification will be overwritten. So I am curious if there is a way to automatically revert the max-width change or override the screen size query when updating to the newest version.
