title: CSS: a:link vs just a (without the :link part)
body: <p>So we're required to use the following order for CSS anchor pseudo-classes    </p>
  
  <pre><code>a:link    { color: red }    
  a:visited { color: blue }  
  a:hover   { color: yellow } 
  a:active  { color: lime }  
  </code></pre>
  
  <p>But my question is why bother with the a:link part? Rather, is there any advantage to the above (other than perhaps clarity) over:</p>
  
  <pre><code>a { color:red; } /* notice no :link part */
  a:visited { color: blue; }
  etc.,etc.
  </code></pre>
