13. XHTML 1.0 Strict Doctype

XHTML 1.0 Strict is ideal for clean structural markup free from layout. XHTML can be used together with the Cascading Style Sheet language (CSS) to achieve desired font, color and layout effects.

The XHTML Strict DTD deprecates many elements and does excludes frameset related elements.

Example 13.1 XHTML 1.0 Strict DTD
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
