layout crashed in mobile view (responsive)

It displays nicely on pc, but when it is viewed through mobile (iphone),
the layout is crashed.

Let’s say i have this code.
[code]
require_once('Smarty/libs/Smarty.class.php');
[/code]

It’s too long to be viewed on iphone, and i was hopping that it will be continued to next line but it’s just displayed as one line.
Due to this, the other contents area in the page is minimized.

Any solution to this?

Thank you.
