H A Dweb-focus.md17 Web组件焦点、焦点链和走焦的详情说明请参考[ArkUI焦点基础概念](../ui/arkts-common-events-focus-event.md#基础概念)。
25 - 网页内元素走焦：指焦点在网页内的元素之间转移的行为。该行为遵循W3C标准，开发者可以通过监听focus（在元素获取焦点时触发）和blur（在元素失去焦点时触发）事件来捕捉这些变化。
28 根据走焦的触发方式，可以分为主动走焦和被动走焦，Web组件走焦规范详情参考[ArkUI走焦规范](../ui/arkts-common-events-focus-event.md#走焦规范)。
