Try <!doctype html> first and then try <!DOCTYPE html> second. Experiment and note down the results. I would stick with caps but if it works without then use that, if you wish.

The specs say it is case-insensitive. https://html.spec.whatwg.org/multipage/syntax.html#syntax-doctype

There is a bit of debate on whether DOCTYPE should be uppercase for backwards compatibility, so use that if you are aiming to support legacy browsers.
