Having recently opened my redesigned site to the public, i've been getting feedback from users that the main iframe hasn't been expanding to fill the size of the contained content. I've tried various methods to sort this problem out but I just can't seem to fix it. Anyone have any ideas? I've been told to use PHP includes, but PHP is my weak point and so i'm treating it as a last resort. You can find the website here. I greatly appreciate any help anyone can offer. Thank you for reading.
