I’d like to put a bottom border around the last row of the grid and a right border around the last column of the grid. The grid should look like this
_________________

___________| |
(2) |
_________________| (3)
(1) is the border-right of the rightmost column.
(2) is the last row in the grid.
(3) is the outer border of the grid element defined in the HTML.
I have (3), the border around the grid, defined in the css. How do I define borders (1) and (2)?
