Scrollbar problems

1

I am currently having trouble with css and html integration within dreamweaver. I wanted to create custom-colored scrollbars for my website, and unfortunately I can only get them to work on one page. I have verified that the css code for my colored scrollbars is correct, and that my css import code to my html file is correct as well. Basically, custom-colored scrollbars don’t show up on all but one of my pages. Could someone please help me out with this problem? Thanks.
