样式p：fileUpload按钮大小

Question

I want to make the PrimeFaces fileload button smaller than the default, and I want to adjust the positions of the buttons. 我想使PrimeFaces文件加载按钮比默认按钮小，并且我想调整按钮的位置。 This is the xhtml file. 这是xhtml文件。

    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. 我当前的按钮已附加。 How to get rid of the outer layer of the box? 如何摆脱盒子的外层？ And how to adjust the distance between "choose" and "upload"? 以及如何调整“选择”和“上载”之间的距离？

Proposal 提案

I used the following css: 我使用了以下CSS：

/* 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;
}

Explanations 说明

visibility:hidden; does not remove the covered space, display:none; 不删除覆盖的空间， display:none; does 确实
the large padding comes from .ui-button-text-icon-left .ui-button-text , so we override that 大的填充来自.ui-button-text-icon-left .ui-button-text ，因此我们将其覆盖
a general rule of thumb: try to avoid !important but find a more specific css selector instead 一般经验法则：尽量避免!important而是找到更具体的CSS选择器
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 Firefox和Chrome等浏览器可让您按F12来检查页面的源代码，并实时预览对html或css内容所做的任何更改

I'm assuming this is the button you're referring to: http://www.primefaces.org/showcase/ui/file/upload/basic.xhtml 我假设这是您指的按钮： 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. 如果是这样，则您的选择仅限于缩小字体，减少填充和/或删除图标。

For example: 例如：

/* 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: 关于注释中的其他问题，您可以使用以下方法删除包含的样式：

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

You can add some margin after the "choose" button with this: 您可以在“选择”按钮之后添加一些边距：

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