HTML Beginning coding Problem with w3 validator-CodePudding

Problem: Error Stray End head Tag, Error body tag seen but an element of the same type was already open, Error stray start footer tag.

Question: Why am I getting these error? I've been looking through my book and can't figure it out.

CodePudding user response：

The start and end tags for the head, body, and html elements are optional.

If you include an element in the head which isn't allowed there (such as h1 or h2 as you have done) then the head will be implicitly closed and the body implicitly started.

This has a knock of effect of making the explicit end tag for head and the start tag for body and error.

Only put elements in the head that are allowed there.

The only elements that are allowed to be children of html are head and body. You can't put a footer there, probably you meant it to be the last child of the body element so it needs to go before the body end tag.

You can't put a footer tag out of a body tag section
