html - 如何设置联系人表单 7 文件输入按钮的样式

Question

我似乎无法定位用于在联系表 7 中上传文件的按钮。我如何定位选择文件按钮以便我可以添加背景颜色等。哦，我也在做这个是 WordPress 以防你需要知道这一点。所以在后端看起来像这样；

<label class="form_label"> Your Name<span>*</span>
[text* your-name]</label>

<label class="form_label"> Your Email<span>*</span>
[email* your-email]</label>

<label class="form_label">Tel
[tel tel]</label>

<label class="form_label">CV<span>*</span>
[file cv id:upload]</label>

<label class="form_label">Cover Letter
[textarea your-message]</label>

[submit "Send"]

我的输出 html 如下所示。

<div role="form" class="wpcf7" id="wpcf7-f47-o1" lang="en-US" dir="ltr">
  <div class="screen-reader-response"></div>
  <form action="/Lester_Goddard_New/#wpcf7-f47-o1" method="post" class="wpcf7-form" enctype="multipart/form-data" novalidate="novalidate">
    <div style="display: none;">

    <p><input type="submit" value="Send" class="wpcf7-form-control wpcf7-submit" /></p>
    <div class="wpcf7-response-output wpcf7-display-none"></div>
  </form>
</div>

我必须更改 visibility:hidden;通过 不透明度:0;

根据 https://www.quirksmode.org/dom/inputfile.html所以按钮继续工作，否则点击不会提示浏览。
