--description--

Welcome to the CSS Variables Skyline project! Start by adding the !DOCTYPE html declaration at the top of the document so the browser knows what type of document it's reading.

--hints--

Your code should contain the DOCTYPE reference.

assert(code.match(/<!DOCTYPE/gi));

You should include a space after the DOCTYPE reference.

assert(code.match(/<!DOCTYPE\s+/gi));

You should define the document type to be html.

assert(code.match(/html/gi));

You should close the DOCTYPE declaration with a > after the type.

assert(code.match(/html\s*>/gi));
