I understand when using certain WP functions like site_url(); you should escape these with the esc_html(); function in the following manner:

<?php esc_html(site_url()) ?>

My question is, if I have inputted the site url manually in a template file such as front-page.php like this:

<a href="//mysite.com">My Site</a>

Do I still need to use the esc_html() function? It doesn't mention anything about this use-case in the docs. And if so how do I go about this?

Many thanks

    esc_html() wouldn't be the correct function for links. You'd use esc_url(), but you don't need to for hard-coded links. – Jacob Peattie Jan 5 '18 at 5:54

Nope, you don't need to escape hard-coded URLs.

    A note on why you don't need to escape hardcoded static strings would be great :) – Tom J Nowell Jan 4 '18 at 23:27
  • But you would need to escape links which are not hardcoded, but populated from backend via an admin? – D. Dan Jan 5 '18 at 12:42
