Multiple CSS files

[angelazou]

Actually, what I want to do is to make the sidebar disappear at the index page, which kind of requires me to write a new header + CSS. However, I think I might have found the answer. I came across the breadcrumbs CSS, it is designed to not display when at index page. I think I can apply this to my sidebar, just modifying it to the index page. But I'm not familiar with this code, can someone please elaborate this?

Code:

#index header .breadcrumbs { display:none; }

Thanks,
