HTML 5 + js make yours website UI design perfect, but for secure functionality u need to add server side script like php, ruby on rails, asp.net etc, js is only client side, which have no websites security.
No, not necessarily. A website needs styling too, and you can't do that with neither HTML nor JS, you'll need CSS! A website also needs something called a 'back-end', which would process any input from the website and perform interactions with your website's database. You can do it with JS, but it isn't the most user-friendly solution
