I'm working on a redesign of navboxes of Dead Ahead: Zombie Warfare Wiki. In particular, I want to change the look of their borders. Here's how one of the boxes looks like ATM. My first question is if it's possible to change the style of border so it looks like a line of solid pixels instead of embedded contour.

I'm aware that "border-style" can be used instead of regular "border", but that setting only applies to a single part of the box, when I need it for the whole thing. So, my second question is if it's possible to remove gaps between parts of the navbox, so they were all close to each other. Version of a navbox I'd like to apply a second option on to.
