21⟩ How To Close an XHTML Element?

Every XHTML element must be closed. There are two ways to close an XHTML element:

► Using a closing tag, which is the element name prefixed with "/" and enclosed in a pair of angle brackets: "<" and ">".

► Closing the opening tag immediately by placing "/" before the ending bracket: ">".

Here are some good examples of closing XHTML elements:

► <html>...</html>- Closing the html element with a closing tag.

► <head>...</head> - Closing the head element with a closing tag.

► <title/> - Closing the title element immediately with no content.

► <body>...</body> - Closing the body element with a closing tag.

► ... - Closing the p element with a closing tag.

► <script/> - Closing the script element immediately with no content.

22⟩ What Is Wrong with My Tags?

If you are used HTML syntax, you may write your tags as in the paragraph below:

I love the way you look at me,

Your eyes so bright and blue.

I love the way you kiss me,

Your lips so soft and smooth.

But that paragraph will be invalid as XHTML documents, because all 4 are not closed. You should change it to:

I love the way you look at me,

Your eyes so bright and blue.

I love the way you kiss me,

Your lips so soft and smooth.

23⟩ What Is Wrong with My <meta> Tags?

If you are converting existing HTML documents to XHTML format, you may find some <meta> tags are written as:

content="Tutorials, FAQs and Tips on XHTML Documents.">

content="XHTML Tutorials, FAQs, Tips">

But all those <meta> tags are invalid in a XHTML document. They must be closed as:

content="Tutorials, FAQs and Tips on XHTML Documents."/>

content="XHTML Tutorials, FAQs, Tips"/>

Note to HTML document authors: <meta> tag syntax in XHTML is the opposite to <meta> tag syntax in HTML. In XHTML, meta tag must be closed. But in HTML, meta tag can not be closed.
