支持轉換和動畫效果的 CSS3 多級菜單實例

在這里我們將創建一個很棒的 CSS3 菜單，使用 UL-LI 。在線演示，源碼下載

首先是一個簡單的 HTML (index.html)：

<!DOCTYPE html>
<html lang="en" >
    <head>
        <meta charset="utf-8" />

        <title>CSS3 multilevel menu with transition and animation | Script Tutorials</title>

        <link href="css/layout.css" type="text/css" rel="stylesheet">
        <link href="css/menu.css" type="text/css" rel="stylesheet">

    </head>
    <body>

        <header>
            <h2>CSS3 multilevel menu with transition and animation</h2>
            <a href="http://www.script-tutorials.com/css3-multilevel-menu-with-transition-and-animation/" class="stuts">Back to original tutorial on <span>Script Tutorials</span></a>

        </header>

        <div class="container">

            <ul id="nav">
                <li>
                    <a href="#">Parent link #1</a>

                    <a href="#">Sub #11</a>
                    <a href="#">Sub #12</a>
                    <a href="#">Sub #13</a>

                    <a href="#">Sub #14</a>
                </li>
                <li>
                    <a href="#">Parent link #2</a>

                    <a href="#">Sub #21</a>
                    <a href="#">Sub #22</a>
                    <a href="#">Sub #23</a>

                    <a href="#">Sub #24</a>
                </li>
                <li>
                    <a href="#">Parent link #3</a>

                    <a href="#">Sub #31</a>
                    <a href="#">Sub #32</a>
                    <a href="#">Sub #33</a>

                    <a href="#">Sub #34</a>
                </li>
                <li>
                    <a href="#">Parent link #4</a>

                    <a href="#">Sub #41</a>
                    <a href="#">Sub #42</a>
                    <a href="#">Sub #43</a>

                    <a href="#">Sub #44</a>
                </li>
            </ul>

        </div>

    </body>
</html>

然后是 CSS (css/menu.css)

ul#nav {
    border: 1px solid #454545;
    display: block;
    height: 400px;
    margin: 0;
    padding: 15px;
    width: 160px;

    -moz-border-radius: 9px;
    -ms-border-radius: 9px;
    -webkit-border-radius: 9px;
    -o-border-radius: 9px;
    border-radius: 9px;

    background: -moz-linear-gradient(#f1f7ff, #d9e1ec);
    background: -ms-linear-gradient(#f1f7ff, #d9e1ec);
    background: -webkit-gradient(linear, left top, left bottom, color-stop(0%, #f1f7ff), color-stop(100%, #d9e1ec));
    background: -webkit-linear-gradient(#f1f7ff, #d9e1ec);
    background: -o-linear-gradient(#f1f7ff, #d9e1ec);
    filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#f1f7ff', endColorstr='#d9e1ec');
    -ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr='#f1f7ff', endColorstr='#d9e1ec')";
    background: linear-gradient(#f1f7ff, #d9e1ec);
}

@-moz-keyframes custom_effect {
    0% {
        background:rgba(255, 255, 255, 0.0);
        height: 60px;
    }
    33% {
        background:rgba(255, 255, 255, 0.0);
        height: 160px;
    }
    66% {
        background:rgba(255, 255, 255, 1.0);
    }
    100% {
        background:rgba(190, 220, 255, 0.8);
        height: 135px;
    }
}
@-webkit-keyframes custom_effect {
    0% {
        background:rgba(255, 255, 255, 0.0);
        height: 60px;
    }
    33% {
        background:rgba(255, 255, 255, 0.0);
        height: 160px;
    }
    66% {
        background:rgba(255, 255, 255, 1.0);
    }
    100% {
        background:rgba(190, 220, 255, 0.8);
        height: 135px;
    }
}
ul#nav li {
    -moz-border-radius: 9px;
    -ms-border-radius: 9px;
    -webkit-border-radius: 9px;
    -o-border-radius: 9px;
    border-radius: 9px;

    background-color:transparent;
    border: 1px solid #454545;
    display: block;
    height: 60px;
    line-height: 60px;
    margin-bottom: 15px;
    overflow: hidden;
}
ul#nav li:hover {
    -moz-animation-name: custom_effect;
    -moz-animation-duration: 0.4s;
    -moz-animation-timing-function: ease;
    -moz-animation-iteration-count: 1;
    -moz-animation-direction: normal;
    -moz-animation-delay: 0;
    -moz-animation-play-state: running;
    -moz-animation-fill-mode: forwards;

    -webkit-animation-name: custom_effect;
    -webkit-animation-duration: 0.4s;
    -webkit-animation-timing-function: ease;
    -webkit-animation-iteration-count: 1;
    -webkit-animation-direction: normal;
    -webkit-animation-delay: 0;
    -webkit-animation-play-state: running;
    -webkit-animation-fill-mode: forwards;

    background:rgba(190, 220, 255, 0.8);
    height: 135px;
}
ul#nav a {
    border-style: none;
    border-width: 0;
    color: #181818;
    cursor: pointer;
    float: left;
    font-size: 13px;
    font-weight: bold;
    line-height: 30px;
    margin-top: 100px;
    padding-left: 18px;
    text-align: left;
    text-decoration: none;
    text-shadow: 0 1px 1px #FFFFFF;
    vertical-align: middle;

    -moz-transition: all 0.1s 0.4s;
    -ms-transition: all 0.1s 0.4s;
    -o-transition: all 0.1s 0.4s;
    -webkit-transition: all 0.1s 0.4s;
    transition: all 0.1s 0.4s;
}
ul#nav a:hover {
    text-decoration: underline;
}
ul#nav li a:first-child {
    display: block;
    float: none;
    line-height: 60px;
    margin-top: 0;
}
ul#nav li:hover a:first-child {
    line-height: 60px;
}
ul#nav li:hover a {
    margin-top: 0;
}

沒了，連圖片都不需要，酷吧:)
