∙ 12y agoThe <!DOCTYPE> declaration must be the very first thing in your HTML document, before the <html> tag.
The <!DOCTYPE> declaration is not an HTML tag; it is an instruction to the web browser about what version of HTML the page is written in.
The <!DOCTYPE> declaration refers to a Document Type Definition (DTD). The DTD specifies the rules for the markup language, so that the browsers render the content correctly.

How do you find the HTML version using code?
Your best bet is going to be looking for a "doctype declaration." For instance <!DOCTYPE html> will precede all HTML 5 pages. The same works for XHTML. The trouble becomes that HTML 4.01, and earlier, will not allow for this. Then you'll be forced to look at the code's tags, specifically, and attempt to work backwards from there. Good luck, by the way. The modern browsers automatically enter a mode of rendering called "quirks mode" whenever a doctype is not declared, or when one is declared, but its standards are not adhered to.
