自定义 Foundation 提供的 scss 默认值或使用您自己的 css 文件覆盖它们。

More in their documentation here .

如果您没有运行 SASS，那么您需要将覆盖样式表放在 Foundation 样式表之后，这样您就不需要做一些愚蠢的事情，例如使用 !important。

在文档的示例中，它们的触发器是一个带有“button”类的按钮，因此您需要重写该类以获得您想要的外观:

<a class="button" data-dropdown="tinyDrop" aria-controls="tinyDrop" aria-expanded="false">Link Dropdown »</a>

就我个人而言，我会添加类似的内容来覆盖而不是更改默认的 .button 样式:

.button.my-dropdown-style {...}
