凸出和折纸效果的导航菜单css3导航代码

凸出和折纸效果的导航菜单css3导航代码。不支持IE8以下浏览器。 第一步、在head区域引入下面的css样式:

<style>
* {
    /* Basic CSS reset */
    margin:0;
    padding:0;
}
body {
    /* These styles have nothing to do with the ribbon */
    background:url(dark_wood.png) 0 0 repeat;
    padding:35px 0 0;
    margin:auto;
    text-align:center;
}
.ribbon {
    display:inline-block;
}
.ribbon:after, .ribbon:before {
    margin-top:0.5em;
    content: "";
    float:left;
    border:1.5em solid #fff;
}
.ribbon:after {
    border-right-color:transparent;
}
.ribbon:before {
    border-left-color:transparent;
}
.ribbon a:link, .ribbon a:visited {
    color:#000;
    text-decoration:none;
    float:left;
    height:3.5em;
    overflow:hidden;
}
.ribbon span {
    background:#fff;
    display:inline-block;
    line-height:3em;
    padding:0 1em;
    margin-top:0.5em;
    position:relative;

    -webkit-transition: background-color 0.2s, margin-top 0.2s;  /* Saf3.2+, Chrome */
    -moz-transition: background-color 0.2s, margin-top 0.2s;  /* FF4+ */
    -ms-transition: background-color 0.2s, margin-top 0.2s;  /* IE10 */
    -o-transition: background-color 0.2s, margin-top 0.2s;  /* Opera 10.5+ */
    transition: background-color 0.2s, margin-top 0.2s;
}
.ribbon a:hover span {
    background:#FFD204;
    margin-top:0;
}
.ribbon span:before {
    content: "";
    position:absolute;
    top:3em;
    left:0;
    border-right:0.5em solid #9B8651;
    border-bottom:0.5em solid #fff;
}
.ribbon span:after {
    content: "";
    position:absolute;
    top:3em;
    right:0;
    border-left:0.5em solid #9B8651;
    border-bottom:0.5em solid #fff;
}
</style>

第二步、在body区域引入下面的代码：

<div class='ribbon'>
    <a href='#'><span>Home</span></a>
    <a href='#'><span>About</span></a>
    <a href='#'><span>Services</span></a>
    <a href='#'><span>Contact</span></a>
</div>
