Cross-Browser Pure CSS Dropdown Navigation


 / Published in: CSS
 

To make the menu work in IE6 (which doesn't support the :hover pseudo element on anything but links and tables), the IE6-specific CSS calls on Whatever:hover. If using Dean Edwards' IE7-js, this is unnecessary as his script fixes li:hover behavior in IE6.

  1. <!--# HTML #-->
  2.  
  3. <ul id="nav">
  4. <li><a href="#">Home</a></li>
  5.  
  6. <li><a href="#">About</a></li>
  7. <li><a href="#">Products</a><ul>
  8. <li><a href="#">Product 1</a></li>
  9. <li><a href="#">Product 2</a></li>
  10. <li><a href="#">Product 3</a></li>
  11. </ul></li>
  12.  
  13. <li><a href="#">Services</a><ul>
  14. <li><a href="#">Service 1</a></li>
  15. <li><a href="#">Service 2</a></li>
  16. <li><a href="#">Service 3</a></li>
  17. </ul></li>
  18. <li><a href="#">Contact</a></li>
  19.  
  20. </ul>
  21.  
  22. <!--# CSS #-->
  23.  
  24. <style type="text/css">
  25. #nav {
  26. list-style:none;
  27. }
  28. #nav li {
  29. float:left;
  30. }
  31. #nav ul {

  33. top:-999px;
  34. width:1px;
