<del>
HTML <del> Tag
The <del> tag specifies a part of the text that was deleted from the document. Browsers display this text as a strikethrough. To indicate a new version of the text, we use the <ins> tag, the content of which is displayed in the browser as underlined.
For displaying the text as underlined, you can use the CSS text-decoration property with the “line-through” value. （>要将文本显示为带下划线，可以将CSS文本装饰属性与"line-through"值一起使用。）
Most screen reading technology doesn’t announce the existence of the <del> tag in the default configuration. If you want to announce it, use the CSS content property with the ::after and ::before pseudo-elements.
