css - 添加自定义 css 以添加此按钮？

Question

我在网站的各个部分使用了 addthis 按钮，我想向它们添加自定义 CSS。我该怎么做？

<a role="button" tabindex="1" class="at-icon-wrapper at-share-btn at-svc-email" style="border-radius: 2px; background-color: rgb(132, 132, 132);">
  <span class="at4-visually-hidden">Share to Email</span>
  <span class="at-icon-wrapper" style="line-height: 32px; height: 32px; width: 32px;">
    <svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" viewBox="0 0 32 32" class="at-icon at-icon-email" style="fill: rgb(255, 255, 255); width: 32px; height: 32px;">
      <g>
        <g fill-rule="evenodd"></g>
        <path d="M27 22.757c0 1.24-.988 2.243-2.19 2.243H7.19C5.98 25 5 23.994 5 22.757V13.67c0-.556.39-.773.855-.496l8.78 5.238c.782.467 1.95.467 2.73 0l8.78-5.238c.472-.28.855-.063.855.495v9.087z"></path>
        <path d="M27 9.243C27 8.006 26.02 7 24.81 7H7.19C5.988 7 5 8.004 5 9.243v.465c0 .554.385 1.232.857 1.514l9.61 5.733c.267.16.8.16 1.067 0l9.61-5.733c.473-.283.856-.96.856-1.514v-.465z"></path>
      </g>
    </svg>
  </span>
</a>

这是单个按钮在控制台中的显示方式，但我不能简单地从此处获取类名并向其添加 CSS，因为它会影响其他按钮，因为它们可能具有相同的类名。
