Rendering the correct UI elements

I am brand new to CSS/HTML/JavaScript and I am having some trouble figuring out how everything connects and works. Right now I have a situation where my selector styles within one page view are being overlooked and my generic cssbutton.css class is taking over the styling of elements on the page. I cannot change the cssbutton.css styles as it will change the styles on every other page as well. I am curious why might my javascript file wont drill in deeper to access the styles I have placed within my planning.css file.

I can add clips of code need be.

If you can share code snippets or a link to the page containing the improperly styled elements, that would be helpful :slight_smile:

Thanks,
Kirupa
