What are XHTML tags?
XHTML tag elements are the basic building blocks of XHTML documents. XHTML tags can be understood as the tags used by the XHTML language to define "what this is, what that is" in an XHTML document.
XHTML tags are keywords surrounded by angle brackets, often appearing in pairs, such as 100db36a723c770d327fc0aef2ce13b173a6ac4ed44ffec12cee46588e518a5e. This tag indicates that this is an hmtl (xhtml) document. The first tag in a tag pair is the start tag, and the second tag is the end tag.
There are also a small number of tags that are not paired or have no end tags, such as line break tags df250b2156c434f3390392d09b1c9563.
XHTML tag closing
In the XHTML specification, all tags must be closed. Usually paired tags are closed with a closing tag, and unpaired tags are closed with a space plus />, such as df250b2156c434f3390392d09b1c9563.
Although the browser can recognize unclosed tags, from a regulatory and long-term perspective, closing tags is necessary.
