Function:Set the width of the upper border of the element.
Note: Only works when the border style is not none. If the border style is none, the border width is actually reset to 0. Negative length values are not allowed.
Note: Always declare the border-style property before the border-top-width property. An element can only change the width of its border after it has acquired it.
