In which browsers? While most adhere to standards when a DOCTYPE is missing or invalid, Internet Explorer (all versions) behave in a very non-standard way, making it very difficult to make designs work in both IE and the rest. About the only *major* difference between standards mode and so-called "quirks mode" (without a DOCTYPE) for most browsers is that width and height of boxes measure outside the borders in "quirks," while in standards mode they measure content only (excluding padding and borders.) CSS is totally borked in IE when you omit the DOCTYPE.
