To make the CSS only apply to the content container while leaving the navigation/header at 100px, you could do this:

body.single .container.grid-container {
    max-width: 800px;
}

codecademy.com has some pretty good beginner courses for CSS.

Personally, I think CSS is one of those things you just need to dive into and make mistakes with – after a while it just makes sense 🙂
