Scroll Box

On all of my website html pages, i have put the information into a scroll box. It was easy to style the first page i did inside the scroll box, but after that I wasnt able to style anything inside it, which is why i was not able to create a proper sign in page where you can type into the box. I was able to do this for my login page but i could not style it so the input boxes and font do not go with the rest of my website. But at least you can type into them!
