What happens if you start with h2 instead of h1

Answer 1

A rip in time and space will occur, which will probably swallow our world into non-existence. Back in 1994 there was an incident involving a computer scientist at MIT, they were barely able to close the rip before it was too late, but unfortunately, we lost a good man that day. :(

Nothing will happen. They're just differing sizes, so use whichever one is appropriate. Many browsers or readers utilize the tags for others purposes, but you should be fine with whatever you choose for your headers.

Answer 2

It's just the hierarchy of headings for your webpage.h1>h2>h3>h4>h5>h6 in size
