[student101]

Every attempt just does not work! How do I get this sprite to work? Is the attached image correct?MENU:

<ul id="nav"><li id="nav_home"><a href="index.php">Home</a></li><li id="nav_about"><a href="about.php">About</a></li><li id="nav_gallery"><a href="gallery.php">Gallery</a></li><li id="nav_services"><a href="services.php">Services</a></li><li id="nav_contact"><a href="contact.php">Contact</a></li></ul>

CSS:

/* Default */#nav {width: 150px;height: 125px;position: relative;background: url(../img/sprite.png);margin: 0;padding: 0;}#nav li {float: left;}#nav li a {position: absolute;top: 0;margin: 0;padding: 0;display: block;height: 25px;background: url(../img/sprite.png) no-repeat;text-indent: -9999px;overflow: hidden;}/*up state*/li#nav_home a {left: 0;width: 150px;background-position: 0 0;}li#nav_about a {top: 25px;width: 150px;background-position: 150px 50px;}li#nav_gallery a {top: 50px;width: 150px;background-position: 150px 100px;}li#nav_services a {top: 75px;width: 150px;background-position: 150px 125px;}li#nav_contact a {top: 125px;width: 150px;background-position: 150px 0;}/*hover state*/li#nav_home a:hover {background-position: 300px 0;}li#nav_about a:hover {background-position: 300px 0;}li#nav_gallery a:hover {background-position: 450px 0;}li#nav_services a:hover {background-position: 435px 0;}li#nav_contact a:hover {background-position: 580px 0;}/*current state*/#body_home li#nav_home a {background-position: 0 -300px;}#body_about li#nav_about a {background-position: -150px -300px;}#body_gallery li#nav_gallery a {background-position: -290px -300px;}#body_services li#nav_services a {background-position: -290px -300px;}#body_contact li#nav_contact a {background-position: -290px -300px;}
