Please visit our sponsors ! The <!doctype> tag
Definition and UsageThe <!doctype> declaration should be the very first thing in your HTML document, before any other element. This tag tells the browser which HTML specification the document uses. In HTML 4.0 you can choose between 3 Document Type Definitions (DTD): Strict DTDThe Strict DTD excludes the presentation attributes and elements that W3C expects to move to a style sheet. If you need to include presentation attributes in your page you can use the Transitional DTD.
Transitional DTDThe Transitional DTD includes presentation attributes and elements that W3C expects to move to a style sheet.
Frameset DTDThe Frameset DTD should be used for documents with frames. This DTD is identical to the Transitional DTD except for: in frameset documents, the frameset element replaces the body element.
