注意的是media属性必须写在下面，从而覆盖上面的css。
<!DOCTYPE HTML> <head> <style> * { margin:0; padding:0; } .ul { background-color:rgb(134, 170, 209); height: 55px; } .ul li { float:left; list-style: none; background-color:rgb(134, 170, 209); width: 20%; height: 100%; } .item { display: block; text-align:center; line-height: 49px; height: 100%; transition: all 0.5s; -moz-transition: all 0.5s; /* Firefox 4 */ -webkit-transition: all 0.5s; /* Safari 和 Chrome */ -o-transition: all 0.5s; cursor:pointer; } .item:hover { background-color:rgb(168, 209, 253); } @media only screen and (max-width: 400px) {/*@media会查询当前屏幕宽度如果小于400时应用一下样式*/ .ul li { width: 100%; height: 100%; } } </style> <script> </script> </head> <body> <header> <ul class="ul"> <li><a class="item">Home</a></li> <li><a class="item">First</a></li> <li><a class="item">Second</a></li> <li><a class="item">Thirdly</a></li> <li><a class="item">Fourth</a></li> </ul> </header> </body> </html>
