Question

I want to make the PrimeFaces fileload button smaller than the default, and I want to adjust the positions of the buttons. This is the xhtml file.

    <title></title>

    <style>
.ui-fileupload-buttonbar .ui-icon {

    margin: 0px 0px 0px 0px !important;
    padding: 0px 0px 0px 0px !important;
    border: none;

    visibility: hidden !important;
}

.ui-button-text-icon-left .ui-button-text {
  font-size: 0.5em;
  color: #339966;  
}
/* Icon */
.ui-button-text-icon-left .ui-icon {
  display: none;
}
.ui-fileupload {
    margin: 0px 0px 0px 0px !important;
    padding: 0px 0px 0px 0px !important;
    display: inline-block;
    border: none;
}
.ui-fileupload-content {
    display: none;
}
</style>

</h:head>
<h:body>

    <h:form>
        <p:fileUpload fileUploadListener="#{fileUploadView.handleFileUpload}"
            mode="advance" dragDropSupport="false" multiple="true"
            update="messages" sizeLimit="100000" fileLimit="3"
            allowTypes="/(\.|\/)(gif|jpe?g|png)$/" />

        <p:growl id="messages" showDetail="true" />
    </h:form>
</h:body>
</html>

My current button is attached. How to get rid of the outer layer of the box? And how to adjust the distance between "choose" and "upload"?

Proposal

I used the following css:

$scope.date1 = Fri Feb 12 2016 12:14:20 GMT-0800 (Pacific Standard Time)
$scope.date2 = Sat Feb 13 2016 12:14:20 GMT-0800 (Pacific Standard Time)
$scope.date3 = Sun Feb 14 2016 12:14:20 GMT-0800 (Pacific Standard Time)
$scope.date4 = Mon Feb 15 2016 12:14:20 GMT-0800 (Pacific Standard Time)

Explanations

/* hide the icons in the file upload button bar */ .ui-fileupload-buttonbar .ui-icon { display: none; } /* adjust the padding of all buttons inside the file upload button bar */ .ui-fileupload-buttonbar .ui-button-text-icon-left .ui-button-text { font-size: 0.8em; padding: 0 0.2em; } /* unstyle the file upload button bar background */ .ui-fileupload-buttonbar.ui-widget-header { background-color: transparent; border: 0 none; } /* increase fileupload button spacing between 'choose' and 'upload' */ .ui-fileupload-buttonbar .ui-fileupload-choose { margin-right: 10em; } /* remove the border of file upload content list */ .ui-fileupload-content { border: 0 none; } does not remove the covered space, visibility:hidden; does
the large padding comes from display:none;, so we override that
a general rule of thumb: try to avoid .ui-button-text-icon-left .ui-button-text but find a more specific css selector instead
browsers like Firefox and Chrome let you inspect the source code of your page by pressing F12 and provide a live preview of any changes made to either html or css content

I’m assuming this is the button you’re referring to: http://www.primefaces.org/showcase/ui/file/upload/basic.xhtml

If so, then your options are limited to making the font smaller, reducing the padding, and/or removing the icon.

For example:

/* Button */
.ui-button-text-icon-left .ui-button-text {
  font-size: 0.8em;
  padding: 0.2em;
}

/* Icon */
.ui-button-text-icon-left .ui-icon {
  display: none;
}

Regarding your additional questions in the comments, you can remove the containing styles with this:

.ui-fileupload-buttonbar {
  background: none;
  border: 0;
  padding: 0;  
}

You can add some margin after the "choose" button with this:

.ui-fileupload-choose.ui-button {
  margin-right: 40px;
}

Style p:fileUpload button size
