推荐答案

简而言之，它使屏幕阅读器看不见该图标，从而增强了可访问性.

In short, it makes the icon not visible to screen readers, to enhance accessibility.

来自文档:

如果您使用图标来添加一些额外的装饰或品牌，则无需在用户浏览您的网站或应用程序时向用户宣布该图标.此外，如果您使用图标在视觉上重新强调HTML或为HTML中已经存在的内容添加样式，则无需对使用辅助技术的用户重复使用该图标.您可以通过将aria-hidden ="true"添加到您的Font Awesome标记中来确保不会被读取.

If you're using an icon to add some extra decoration or branding, it does not need to be announced to users as they are navigating your site or app aurally. Additionally, if you're using an icon to visually re-emphasize or add styling to content already present in your HTML, it does not need to be repeated to an assistive technology-using user. You can make sure this is not read by adding the aria-hidden="true" to your Font Awesome markup.
