title: Use HTML Div to add border only on top and bottom?
body: <p>I use HTML DIV tag to format my header with border like this:</p>
  
  <pre><code>&lt;h3 style="background-color:red; padding:2% 0 2% 0; border:5px solid green"&gt;
  This is a header
  &lt;/h3&gt;
  </code></pre>
  
  <p>However, I would like to have the border appears only on top and bottom, but not on left and right. I would like border in the same way as padding for top left bottom and right, but border does not have this feature(or I don't know?). Is there any way in CSS style to do that?</p>
