That can be done for example in this way(the restart button will be visible only after the end of each game):

Answer 2

Get used to put each language (HTML, CSS and JS) in the corresponding tab. That makes your code more organized, readable and mantainable. Just remember to wrap the JS part in an onLoad function, so it only loads after HTML part is loaded, then all elements exist.
That said, just wrap the code in an infinite loop, which prompts the user at its end to just press the button.
