title: What is the real difference between strict and transitional doctype
body: <p>I have read many forums which explains the difference between strict and transitional doctypes but none of them explain whether selecting strict or transitional matters when it comes to rendering a page. for eg: 'i' tag is deprecated in strict doctype. But it renders fine in your web page no matter you use either of the doctypes. So do other deprecated tags such as 'u' or 'font' for that matter. So my question is, is there a real difference between strict and transitional doctypes when it comes to page rendering.</p>
