CSS Border - Individual Sides
From the examples on the previous pages, you have seen that it is possible to specify a different border for each side.
In CSS, there are also properties for specifying each of the borders (top, right, bottom, and left):
p {
border-top-style: dotted;
border-right-style: solid;
border-bottom-style: dotted;
border-left-style: solid;
}
