Quite a few people have asked me about this now. So here is a full tutorial/documentation on how to do it, with complete instructions, including how to use multiple boxes of different sizes.

This includes the following files;

Scrolling Boxes CSS
Using more than one box
Journal Entry
Preview

This is now a .zip file. If you would prefer a .rar, just drop a comment and I'll up one for you.

DO NOT USE MY CODES. IT WILL NOT WORK. IF YOU FOLLOW THE DOCUMENTATION YOU WILL KNOW WHY RATHER EASILY. ITS A MATTER OF CLASS NAMES, AND IF YOU DON'T UNDERSTAND WHAT I'M ON ABOUT, YOU OBVIOUSLY DIDN'T LEARN SO GO OVER IT UNTILL YOU DO. IF YOU TRY AND COME TO ME LIKE THE PAST FEW HUNDRED PEOPLE SAYING "IT DOESN'T WORK!" I'M GOIN TO SCREAM. YOU'RE SUPPOSED TO LEARN HOW TO DO IT YOURSELF, NOT TAKE MY CODE.

You do not have to credit me in your Journal CSS if you use this if you do not want to, but I'd appreciate it if you left a comment to let me know you used it and added it to your favourites if it was useful. Especially if you use my template!

Please don't note me with questions about using this, please leave a comment on this deviation. That way, if someone else has a similar issue, I can try and avoid repeating myself.

In the preview, a header THEN the scroll box is shown.
This tutorial is for the SCROLLBOX ONLY.

EDIT: HOLY CRAP A DD. I'm gobsmacked. I went to sleep feeling like shap last night. Yes shap, its a word I invented, and if you can't guess what words I put together there, you may still be calling people "poo-poo head" But yez, so to wake up to a DD was a really, really nice surprise, it hadn't ever even crossed my mind, so seeing some "congrats on the DD" comments made me have to check and do a double take! Thank you, Anni, for suggesting me! If you don't know her already, go and visit her over at =soulful-tears because she's so damn lovely.
