How to include external HTML file into another HTML?

Answer 1

That is very usefull and very common. But it’s always done in the server side.

<?php
include(”root.php”);
?>

This is one of the reason why I like to use laravel and django. They have a proper templating engines.

Answer 2

Well say I have two separate HTML files. One is the root and the other is external HTML file on my computer and I want to merge/combine the two.
