Guess My Number - guess validation

It might be a good idea to add maximum and minimum limits on the input field where the user enters the guess number.

Files:
05-Guess-My-Number/starter/index.html (link to file)
05-Guess-My-Number/final/index.html (link to file)

Current code (line 19):
<input type="number" class="guess" />

Suggested code:
<input type="number" class="guess" min="1" max="20" />

This validation could be done in JavaScript in the game's logic but would be good if learners get used to implementing such validations in HTML itself; would be good user experience as well.
