自定义控件(Custom Controls)
描述 (Description)
日期选择器，开关或滑块等自定义控件需要一些注意才能访问它。 使用标签帮助文本或自定义输入，需要添加aria-labelledby和aria-describedby属性。 这将有助于屏幕阅读器描述控件。
例子 (Example)
以下示例演示了在Foundation中使用custom controls 。

<body>
<form>
<label id = "rateLabel">Rate Yourself</label>
<div class = "slider" aria-labelledby = "rateLabel" aria-describedby = "rateHelpText"
data-slider data-initial-start = '80' data-end = '100'>
<span class = "slider-handle" data-slider-handle role = "slider" tabindex = "1"></span>
<span class = "slider-fill" data-slider-fill></span>
