Referring to this page as my source, I understand the purpose of hover,
visited, and active, but what the heck is "focus"?

Then to confuse me a tad more, he uses a line like -- body.section-1 #menu
ul#subnav-1,.

Obviously, this guy knows how to truly manipulate css. I kind of understand
how you can sub-define classes so you don't have to repeat the coding. But
in the "body"? He does this four times to create his menu with.

I'm open for clues.

When the element has the focus. Common example is <input> elements, when the
user can type in to the element, it has the focus. The other common example
is hyperlinks is tab-based (as opposed to mouse-based) navigation.

Then to confuse me a tad more, he uses a line like -- body.section-1 #menu
ul#subnav-1,.

There is no such thing as a sub-class in CSS.

But in the "body"? He does this four times to create his menu with.

Some pages will have <body class="section-1"> some will have <body
class="section-2"> and so on. Presumably different menu sections and
visible depending on which section its in.

"The :focus pseudo-class applies while an element has the focus (accepts
keyboard events or other forms of text input)."

So does this mean that if someone were to press enter instead of clicking
the action would happen anyway?

What action? :focus just suggests how an element should look when it has the
focus, it doesn't define any action. If a textarea has the focus, then
pressing enter creates a new line in that textarea.

Have you never heard of "keyboard navigation"?

Cheers

Yes. Only problem is, very few sites use it.

Users use keyboard navigation, not sites. Are you sure you know what rf
is talking about?
