I think I made a mistake long ago of making .html extensions for my web pages in one site.
Now I want to do things like import divs, and make things modular, but I have a feeling it is not possible.
In PHP I could do something like
<?php
include("divs/footer.php");
?>
But how could I import a div in a page with a .html extension? Or does the .html extension not matter?
Thanks!
The extension does not matter.
