title: How to change css of an id element, when hovering over any link in website?
body: <p>Regardless of where the links are in the html, if i hover over one, for example, an image could change, the background could change, or whatever... anywhere in the site.</p>
  
  <p>best answer = simple way without javascript<br>
  good enough = elegant way using javascript</p>
  
  <hr>
  
  <p>edit: i already know about this...</p>
  
  <pre><code>a:hover ~ #b{
      background: red;
  }
  </code></pre>
  
  <p>"~ #b" = next siblings</p>
  
  <p>"+ #b" = first next sibling</p>
  
  <p>" #b" descendant of a</p>
  
  <p>that just effects siblings. what if they have completely different parents?</p>
  
  <p>if there's any neat tricks, website design. that's what i'm looking for.</p>
