Using with Bootstrap
You can use this uploader with Bootstrap framework without writing much additional CSS. Just add the following CSS to your page to hide the browser's "browse" button:
css
#id-of-uploader .btn {
cursor: pointer;
display: inline-block;
position: relative;
overflow: hidden;
}#id-of-uploader .btn input {
top: -10px;
right: -40px;
z-index: 2;
position: absolute;
cursor: pointer;
opacity: 0;
filter: alpha(opacity=0);
font-size: 50px;
}
