If you aspire to be a professional, you have to write standards-compliant web pages. By specifying the correct Document Type Declaration (or doctype) you make sure that the browser knows which standards to follow when rendering your web page.

Commonly used doctypes

Below are listed the doctypes that see extensive use today.

HTML 4.01 Strict


HTML 4.01 Transitional


HTML 3.2 Final


XHTML 1.0
