When changing the file includes/languages/english/header.php to read:
define('HEADER_SALES_TEXT', 'Just when you thought it couldn't get any better!');
and I refresh the store front I get a "Page not working".
I realized that I had to delete the single quote in "couldn't," and make it two words:
define('HEADER_SALES_TEXT', 'Just when you thought it could not get any better!');
In order for the page to load properly.

Is there another way of writing this code?
I do want the tagline to read:
"Just when you thought it couldn't get any better!"


Also.....

How do I change the font size and make it italic?
