From HTML to XHTML is not difficult. HTML XHTML different from the rules are as follows:
1.XHTML document to declare the beginning of DTD.
2. You need for your <html> Tags add a namespace.
And on the DTD namespace Please refer to the content of XHTML Tutorial - head and DTD.

6 If you use the strict.dtd. Is the most stringent XHTML, many of the attributes defined appearance will be barred.
For example, if you add links to the picture at the same time to remove the frame. >,They must be achieved through CSS. Can no longer use <img src ="..." border = "0" />, but rather must be achieved through CSS. We recommend you use strict.dtd, give up all the definition of appearance attributes, and the use of fully defined CSS pages appearance.
