No, it's your web browsers html engine that detects a faulty html tag 
with another html tag and tries it best to correct the html and shows 
you what it thinks should be shown.

Had you written:

<?php echo 1+1; ?>

your output had been:


yes, nothing at all, and that is the proof of that the php code do not 
be executed, had the php engine processed the page before sent to you, 
you would have had a 2.

As long it's in a file ending with html/htm it will not be executed, so 
matter what you write, nothing will happen, you need to change the 
ending to php.

You just need to change the links to the new page name that ends with 
.php and that's it.

Itnernet is nowadays quite useless without javascript, so people tend to 
not disable it anymore. The benefit with the javascript is that you can 
display time the file was modified based on the users timezone.
