1、新建html文档。
2、书写hmtl代艨位雅剖码。<section class="demo"><稆糨孝汶;ul class="nav black"> <li><a href="">Home</a></li> <li><a href="">About Me</a></li> <li><a href="">Portfolio</a></li> <li><a href="">Blog</a></li> <li><a href="">Resources</a></li> <li><a href="">Contact Me</a></li></ul><ul class="nav red"> <li><a href="">Home</a></li> <li><a href="">About Me</a></li> <li><a href="">Portfolio</a></li> <li><a href="">Blog</a></li> <li><a href="">Resources</a></li> <li><a href="">Contact Me</a></li></ul><ul class="nav blue"> <li><a href="">Home</a></li> <li><a href="">About Me</a></li> <li><a href="">Portfolio</a></li> <li><a href="">Blog</a></li> <li><a href="">Resources</a></li> <li><a href="">Contact Me</a></li></ul><ul class="nav green"> <li><a href="">Home</a></li> <li><a href="">About Me</a></li> <li><a href="">Portfolio</a></li> <li><a href="">Blog</a></li> <li><a href="">Resources</a></li> <li><a href="">Contact Me</a></li></ul></section>
3、书写css样式。<style>* { margin: 0; padding: 0; list-style-type: none; }body { background: #ebebeb; }.nav { width: 560px; height: 50px; font: bold 0/50px Arial; text-align: center; margin: 40px auto 0; border-radius: 8px; }.nav a { display: inline-block; -webkit-transition: all 0.2s ease-in; -moz-transition: all 0.2s ease-in; -o-transition: all 0.2s ease-in; -ms-transition: all 0.2s ease-in; transition: all 0.2s ease-in; }.nav a:hover { -webkit-transform: rotate(10deg); -moz-transform: rotate(10deg); -o-transform: rotate(10deg); -ms-transform: rotate(10deg); transform: rotate(10deg); }.black { background: #2c2c2c; box-shadow: 0 7px 0 #0b0b0b; }.red { background: #f65f57; box-shadow: 0 7px 0 #ba4a45; }.blue { background: #36b7e5; box-shadow: 0 7px 0 #3595b8; }.green { background: #9cd564; box-shadow: 0 7px 0 #86b65b; }.nav li { position: relative; display: inline-block; padding: 0 16px; font-size: 13px; text-shadow: 1px 2px 4px rgba(0,0,0,.5); list-style: none outside none; }.nav li::before, .nav li::after { content: ""; position: absolute; top: 14px; height: 25px; width: 1px; }.nav li::after { right: 0; background: -moz-linear-gradient(top, rgba(255,255,255,0), rgba(255,255,255,.2) 50%, rgba(255,255,255,0)); background: -webkit-linear-gradient(top, rgba(255,255,255,0), rgba(255,255,255,.2) 50%, rgba(255,255,255,0)); background: -o-linear-gradient(top, rgba(255,255,255,0), rgba(255,255,255,.2) 50%, rgba(255,255,255,0)); background: -ms-linear-gradient(top, rgba(255,255,255,0), rgba(255,255,255,.2) 50%, rgba(255,255,255,0)); background: linear-gradient(top, rgba(255,255,255,0), rgba(255,255,255,.2) 50%, rgba(255,255,255,0)); }.black li::before { left: 0; background: -moz-linear-gradient(top, #2c2c2c, #000 50%, #2c2c2c); background: -webkit-linear-gradient(top, #2c2c2c, #000 50%, #2c2c2c); background: -o-linear-gradient(top, #2c2c2c, #000 50%, #2c2c2c); background: -ms-linear-gradient(top, #2c2c2c, #000 50%, #2c2c2c); background: linear-gradient(top, #2c2c2c, #000 50%, #2c2c2c); }.red li::before { left: 0; background: -moz-linear-gradient(top, #ff625a, #9e3e3a 50%, #ff625a); background: -webkit-linear-gradient(top, #ff625a, #9e3e3a 50%, #ff625a); background: -o-linear-gradient(top, #ff625a, #9e3e3a 50%, #ff625a); background: -ms-linear-gradient(top, #ff625a, #9e3e3a 50%, #ff625a); background: linear-gradient(top, #ff625a, #9e3e3a 50%, #ff625a); }.blue li::before { left: 0; background: -moz-linear-gradient(top, #34b0dc, #237a99 50%, #34b0dc); background: -webkit-linear-gradient(top, #34b0dc, #237a99 50%, #34b0dc); background: -o-linear-gradient(top, #34b0dc, #237a99 50%, #34b0dc); background: -ms-linear-gradient(top, #34b0dc, #237a99 50%, #34b0dc); background: linear-gradient(top, #34b0dc, #237a99 50%, #34b0dc); }.green li::before { left: 0; background: -moz-linear-gradient(top, #9cd564, #7aa450 50%, #9cd564); background: -webkit-linear-gradient(top, #9cd564, #7aa450 50%, #9cd564); background: -o-linear-gradient(top, #9cd564, #7aa450 50%, #9cd564); background: -ms-linear-gradient(top, #9cd564, #7aa450 50%, #9cd564); background: linear-gradient(top, #9cd564, #7aa450 50%, #9cd564); }.nav li:first-child::before { background: none; }.nav li:last-child::after { background: none; }.nav a, .nav a:hover { color: #fff; text-decoration: none; }</style>
4、代码整体结构。
5、查看效果。第二张是鼠标一上去之后，看第一行第一个。
