推荐答案

HTML5 ARIA 属性就是你要找的.即使没有引导程序，它也可以在您的代码中使用.

HTML5 ARIA attribute is what you're looking for. It can be used in your code even without bootstrap.

Accessible Rich Internet Applications (ARIA) defines ways to make Web content and Web applications (especially those developed with Ajax and JavaScript) more accessible to people with disabilities.

准确来说，您的属性被称为ARIA 属性状态和模型

To be precise for your question, here is what your attributes are called as ARIA attribute states and model

aria-labelledby:标识标记当前元素的元素(或多个元素).

aria-labelledby: Identifies the element (or elements) that labels the current element.

aria-hidden (state):表示元素及其所有后代在实现时对任何用户都不可见或感知作者.

aria-hidden (state): Indicates that the element and all of its descendants are not visible or perceivable to any user as implemented by the author.
