How to style "input file" with CSS3 / Javascript?

I made a custom style for this as well. Check it out

JS Fiddle Demo - Custom Input type="file"

HTML

<input type="file" id="test">
<div class="button-group"> 
<a href="#" id="browse" class="button primary">Browse</a>
<a href="#" id="save" class="button">Save</a>
<a href="#" id="clear" class="button danger">Clear</a>
</div>
<input type="text" id="testfile"></input>

CSS

body {
padding:100px;
}
input[type="file"] {
position:absolute;
display:none;
}
#testfile {
height: 26px;
text-decoration: none;
background-color: #eee;
border:1px solid #ccc;
border-radius:3px;
float:left;
margin-right:5px;
overflow:hidden;
text-overflow:ellipsis;
color:#aaa;
text-indent:5px;
}
#actionbtnBrowse, #actionbtnSave {
margin:0 !important;
width:60px;
}

JQuery

$("#browse").click(function () {
$("#test").click();
})

$("#save").click(function () {
alert('Run a save function');
})

$("#clear").click(function () {
$('#testfile').val('');
})

$('#test').change(function () {
$('#testfile').val($(this).val());
})
