Correct to some extent, and one can do some very
interesting styling things.

For instance:

a:before { content: 'Hyperlink: '; }

will put 'Hyperlink: ' before each and every hyperlink --
and each and every anchor as well, which is not usually desired
behavior, but that can be amended by looking for attributes:

a[href]:before { content: 'Hyperlink: '; }
a[name]:before { content: 'Anchor: '; }

If one wishes, one can use "class".  For HTML, this is
done e.g.

a[href].special:before { content: 'Hyperlink: '; }

so now anything with <a class="special" href="...">
gets a little extra warning. [*]

One can also use name= or id=, though arguably the
<div> tag is a more appropriate target than <a>, for
constructs such as

a#unique:before { content: 'This Unique Link: '}

One can of course stylize this text as one wishes;
one might, for instance, consider the following to be pretty.

a[href]:before { content: 'HYPERLINK: '; color: white; background-color:
blue; font-family: Helvetica; font-weight: bold; font-variant:

One can also of course customize the actual link text as well:

a[href] { display: block; color: white; background-color: green; /* etc */ }

'display: block' puts the link on its own line (and
highlights the entire line in green, which may not be to
everyone's liking).

One can now append something afterwards:

a[href]:after { content: '(END LINK)'; color: white; background-color:
red; font-family: Helvetica; font-weight: bold; font-variant:

If one wants to be silly (or hide irrelevant details,
though there are better methods),

a[href] { display: none }

should *hide* all hyperlinks.

One can also do all sorts of things with position, margin,
padding, top, left, right, bottom, width, and height.  I'll
refer the reader to http://www.w3.org/TR/CSS21 for the details.

Of course, code such as Javascript embedded in the page cannot
be modified using CSS, though said code might be able to read
style instructions -- I'd have to look.

[*] for non-HTML contexts one must use the selector

Linux.  Because it's not the desktop that's
important, it's the ability to DO something
with it.
