Step 1. Insert this code where you want the scrollbox to be.
Step 2. Insert this code in your CSS box before any other code.
Adjust the height and width to your likings. You must have content in the scroll box for it to appear.
Note: If you want to add more than one scroll box you will need to name each individual class name
EX: <div class="scrollbox1"> is one box. <div class="scrollbox2"> is another box, and so on...
