Automatically adjusting page width when viewing entry

Hey everyone,

Just having a bit of trouble with getting my website to add the ability to scroll to the side when viewing some of my more wider entries.

Just to explain, I have no problem getting the website to permanently have a side scrolling bar, but that’s not what I want, as it’s not very attractive. I only want it to come up when you click on the entries that would require one. I’ve left the top most entry (Lisa) there with an image larger than my allocated width on purpose so you can see what I mean.

Here’s my stylesheet for your ease of reference. Hope you guys have a solution! Any help is greatly appreciated.

Thanks in advance.
