<del>:已删除的文本元素
<del> HTML 元素表示已从文档中删除的文本范围。例如，这可以在渲染 "跟踪变化" 或源代码差异信息时使用。<ins> 元素可用于相反的目的：指示已添加到文档中的文本。
¥The <del> HTML element represents a range of text that has been deleted from a document. This can be used when rendering "track changes" or source code diff information, for example. The <ins> element can be used for the opposite purpose: to indicate text that has been added to the document.

¥Accessibility concerns
大多数屏幕阅读技术在其默认配置中均未声明 del 元素的存在。可以使用 CSS content 属性以及 ::before 和 ::after 伪元素来声明它。
¥The presence of the del element is not announced by most screen reading technology in its default configuration. It can be made to be announced by using the CSS content property, along with the ::before and ::after pseudo-elements.
del::before,
del::after {
clip-path: inset(100%);
clip: rect(1px, 1px, 1px, 1px);
height: 1px;
overflow: hidden;
position: absolute;
white-space: nowrap;
width: 1px;
}
del::before {
content: " [deletion start] ";
}
del::after {
content: " [deletion end] ";
}
一些使用屏幕阅读器的人故意禁止播放会造成额外冗长的内容。因此，重要的是不要滥用此技术，并且仅在不知道内容已被删除会对理解产生不利影响的情况下应用它。
¥Some people who use screen readers deliberately disable announcing content that creates extra verbosity. Because of this, it is important to not abuse this technique and only apply it in situations where not knowing content has been deleted would adversely affect understanding.
