CSS在这里可以做很多事情…耍点小花招……

<div id='wrapper'>
    <input type='file' id='browse'>
</div>
<style>
    #wrapper {
            width: 93px; /*play with this value */
            height: 28px; /*play with this value */
            background: url('browseBtn.png') 0 0 no-repeat;
            border:none;
            overflow:hidden;
    }

    #browse{
            margin-left:-145px; /*play with this value */
            opacity:0; /* set to .5 or something so you can better position it as an overlay then back to zero again after you're done */
            -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";
            filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=0);
    }
</style>

我发现插件解决方案太笨重了，所以我制作了自己的jQuery插件Drolex FileStyle。

This plug-in allows you to style file input fields however you want. Actually, you style div elements to look like a tricked out file input, and the actual file input is automatically overlaid with 0% opacity. No additional HTML is required. Just include the css and js files in the page you want Drolex FileStyle and that's it! Edit the css file to your liking. Don't forget the jQuery library if your page doesn't already have it. If the client does not run JavaScript, then the file input will not be modified by js or css.

测试工作在Chrome 24, Firefox 18, Internet Explorer 9。 预计可以在之前的版本中使用。

只有CSS

使用这个非常简单和容易

.choose: -webkit-file-upload-button { 颜色:白色; 显示:inline-block; 背景:# 1 cb6e0; 边界:没有; 填充:7px 15px; 粗细:700; border - radius: 3 px; 空白:nowrap;} 光标:指针; 字体大小:10 pt; ｝ <label>附加你的屏幕短片</label> <input type="file" multiple class=" select ">

如果你正在寻找一个javascript库开箱即用的解决方案，jquery-fileinput工作得很好。

一个快速粗暴的方法是将标签设置为按钮，并将位置设置为绝对，这样它就会浮动在原始按钮上，你仍然可以看到文件名。不过，我正在考虑移动解决方案。

我能想到的唯一方法是在它被渲染后用javascript找到按钮，并分配一个样式给它
