Add border-{top,bottom,left,right}-1

Created by: TheZoker

When I want to have a border only on the bottom, I need to add a border on all sides and remove then afterwards: So the code looks like: border border-left-0 border-top-0 border-right-0 border-dark Which would be much easier, if there was a border-bottom-1

Also, there is no way to match a border the border color of a card. So maybe add another border-grey or something to match that color.

Since I try to re-create the page-title class with utility classes, this would be very helpful. Because a simple mb-3 pb-1 border-bottom-1 border-grey would do the trick
