Setting the Document DTD
• To apply the XHTML 1.0 strict DTD, add the following line after the XML declaration:
<!DOCTYPEƒhtmlƒPUBLICƒ“-//W3C//DTDƒXHTMLƒ1.0ƒStrict//EN”
• To apply the XHTML 1.0 transitional DTD, use the following:
<!DOCTYPEƒhtmlƒPUBLICƒ“-//W3C//DTDƒXHTMLƒ1.0ƒTransitional//EN”
• To apply the XHTML 1.0 frameset DTD, use the following:
<!DOCTYPEƒhtmlƒPUBLICƒ“-//W3C//DTDƒXHTMLƒ1.0ƒFrameset//EN”
• For HTML5 or XHTML5 documents, use the following:
<!DOCTYPEƒhtml>
Tom suggests that you associate the Wizard Works Web site with the transitional DTD
for XHTML 1.0. To do that, you'll add the DOCTYPE declaration for XHTML 1.0 tran-
sitional. Because the code for a DOCTYPE declaration can be long and complicated, a
text file with the declarations from Figure 9-11 has been created for you to copy from.
