问题
I want to make my current website responsive. It's a huge dynamic website and I do not want to make a separate website for mobile or change the <Doctype> or <html>. Is it possible to insert a script that changes the <Doctype> and <html> tags if a website is accessed via a mobile?

No need to change any tags. This is what Media queries are for.
