css input[type=file] 样式美化

思路:

input file上传按钮的美化思路是,先把之前的按钮透明度opacity设置为0,然后,外层用div包裹,就实现了美化功能。

HTML之DOM结构

<a href="javascript:;" class="a-upload">
    <input type="file" name="" id="">点击这里上传文件
</a>

<a href="javascript:;" class="file">选择文件
    <input type="file" name="" id="">
</a>
/*a  upload */
.a-upload {
    padding: 4px 10px;
    height: 20px;
    line-height: 20px;
    position: relative;
    cursor: pointer;
    color: #888;
    background: #fafafa;
    border: 1px solid #ddd;
    border-radius: 4px;
    overflow: hidden;
    display: inline-block;
    *display: inline;
    *zoom: 1
}

.a-upload  input {
    position: absolute;
    font-size: 100px;
    right: 0;
    top: 0;
    opacity: 0;
    filter: alpha(opacity=0);
    cursor: pointer
}

.a-upload:hover {
    color: #444;
    background: #eee;
    border-color: #ccc;
    text-decoration: none
}

前后样式
