基金会 - 屏幕阅读器演示

描述

它隐藏内容，同时阻止屏幕阅读器读取内容。你可以隐藏内容，通过使用 show-for-sr 类，让屏幕阅读器可以读取该内容。

示例

以下示例演示了在 Foundation 中使用 .show-for-sr 类：

<!doctype html>
   <head>
      <meta charset = "utf-8" />
      <meta http-equiv = "x-ua-compatible" content = "ie = edge" />
      <meta name = "viewport" content = "width = device-width, initial-scale = 1.0" />

      <title>Show Screen Readers</title>
