XHTML - Summary

We assume you have understood all the concepts related to XHTML. Therefore, you should be able to write your HTML document into a well-formed XHTML document and get a cleaner version of your website.

Converting HTML to XHTML

You can convert your existing HTML website into XHTML website.

Let us go through some important steps. To convert your existing document, you must first decide which DTD you are going to adhere to, and include document type definition at the top of the document.

  • Make sure you have all other required elements. These include a root element <html> that indicates an XML namespace, a <head> element, a <title> element contained within the <head> element, and a <body> element.

  • Convert all element keywords and attribute names to lowercase.

  • Ensure that all attributes are in a name="value" format.

  • Make sure that all container elements have closing tags.

  • Place a forward slash inside all standalone elements. For example, rewrite all <br> elements as <br />.

  • Designate client-side script code and style sheet code as CDATA sections.
