Question

Say, if I have a website http://website.com/

How do I allow each of my navigation tabs to load a new page with the address, for example, http://website.com/?=newpage

What file names should my other html pages be?

Answer 1

There are no different files to load the content from, it is simply a GET variable with a value in URL, you need Server side or jQuery to load the respective content on your page

PHP For Example

<?php
if(isset($_GET['page']) && $_GET['page'] == 'first_page') {
?> 
Whatever you type in here shows when url is like www.example.com?page=first_page
<?php
} elseif($_GET['page']) && $_GET['page'] == 'second_page') {
?>
Whatever you type in here shows when url is like www.example.com?page=second_page
<?php
}
?>
