Question

我在网上搜索了近两个小时，甚至没有找到一个css样式选择下拉列表的例子。最重要的是我对z-index感兴趣，以显示绝对div块下的选择下拉列表。唯一建立的是造型偏移，背景颜色和字体，但其他css属性呢？搜索webkit shadow dom也没有结果。真的这不可能吗？ :(

Answer 1

使用CSS3选择样式框：

<强> HTML：

<label>
    <select>
        <option selected> Select Box </option>
        <option>Short Option</option>
        <option>This Is A Longer Option</option>
    </select>
</label>

<强> CSS：

body, html { 
    background:#444;
    text-align:center;
    padding:50px 0;
}

select {
    padding:3px;
    margin: 0;
    -webkit-border-radius:4px;
    -moz-border-radius:4px;
    border-radius:4px;
    -webkit-box-shadow: 0 3px 0 #ccc, 0 -1px #fff inset;
    -moz-box-shadow: 0 3px 0 #ccc, 0 -1px #fff inset;
    box-shadow: 0 3px 0 #ccc, 0 -1px #fff inset;
    background: #f8f8f8;
    color:#888;
    border:none;
    outline:none;
    display: inline-block;
    -webkit-appearance:none;
    -moz-appearance:none;
    appearance:none;
    cursor:pointer;
}

/* Targetting Webkit browsers only. FF will show the dropdown arrow with so much padding. */

@media screen and (-webkit-min-device-pixel-ratio:0) {
    select {padding-right:18px}
}

label {position:relative}
label:after {
    content:'<>';
    font:11px "Consolas", monospace;
    color:#aaa;
    -webkit-transform:rotate(90deg);
    -moz-transform:rotate(90deg);
    -ms-transform:rotate(90deg);
    transform:rotate(90deg);
    right:8px; top:2px;
    padding:0 0 2px;
    border-bottom:1px solid #ddd;
    position:absolute;
    pointer-events:none;
}
label:before {
    content:'';
    right:6px; top:0px;
    width:20px; height:20px;
    background:#f8f8f8;
    position:absolute;
    pointer-events:none;
    display:block;
}

这是代码。

body {
    margin-top:20px;
    margin-left:20px;
}
select {
    padding:9px;
    margin: 0;
    border-radius:4px;
    -webkit-box-shadow: 
        0 0px 0 #ccc,
        0 0px #fff inset;
    background: url('http://i45.tinypic.com/309nb74.png') no-repeat right, -moz-linear-gradient(top, #FBFBFB 0%, #E9E9E9 100%);
    background: url('http://i45.tinypic.com/309nb74.png') no-repeat right, -webkit-gradient(linear, left top, left bottom, color-stop(0%,#FBFBFB), color-stop(100%,#E9E9E9));
    color:black;
    border:none;
    outline:none;
    display: inline-block;
    -webkit-appearance:none; 
    cursor:pointer;
    border: 1px solid #ccc;
}
