How do I make an html website template?


How do I make a template using html, so that if I need to change the whole website, I only have to change 1 page? Because when you have like 50 pages e.g. home.html,contactus.html, policies.html etc, but you discover that you spelt the link “Hoome” wrong, you have to edit every single page to rename it to “Home”. How do I get around this? Is there a shortcut?
