Theme Structure
When you first open the /theme/templates folder you may ask: What is frame.php, and where's my header.php and footer.php?
Answer: Gone, never to return. Alright, that might be a little much but there really isn't any point in having your header, footer and navigation in seperate files if you don't have to and because Skeleton uses an output buffer, we don't have to.
Your entire site is held inside of /theme/templates/frame.php. You can of course make a header.php, footer.php, navigation.php and any other files to include if you like, but you don't have to. All the output created in the /modules and /theme/templates files is rendered smack in the middle of frame.php. Open it up to see what I mean.
