<li>If you specify three values, like: div {border-width: thick thin medium}-
the top border will be thick, left and right border will be thin, bottom
border will be medium</li>
<li>If you specify four values, like: div {border-width: thick thin medium
10px} - the top border will be thick, right border will be thin, bottom
