Unless you have more than one navigation on the page and want to do
the highlighting via a body id and the class selector on both of them.

However, as sexy as highlighting with CSS only is, it does not make
sense from a usability/accessibility point of view, as the current
page _should not be a link_. Personally I highlight the current page
with a strong - as this also makes sense without CSS and use the body
id coupled with the nav id and the strong to apply the style.

Hmm, that is an absolute that may be a relative (oh dear, what a bad
one). Specificity concerns might mean that you need both the element
and the ID selector to apply your style. Especially with links as your
nav might be in a #container and there is a #container a {} style.

a .moreinfo for a P and a link.

@import also gets cached and it will not show up on buggy old

Start a blog, add a page to the wiki. This is where I put things like
that, as it is meant to be remembered, right?

Yes, that's absolutely correct.

Correct again (in my opinion).

Sure, if specificity is an issue, by all means, throw some more tags in
there and get specific. However, that #id *is* awfully specific, as it
refers to exactly ONE item on the page. If you have a rule for
#container a {} and want new rules for #container #foo {} just give it
the rules - anything that requires overriding has to be explicitly set
in any case. What would be the difference between #container #foo {} and
#container a#foo {} if you want to override #container a {} rules?
There's no point in specifying a#foo.

Well, yes. I think that's obvious.

I think the idea was that the wiki would stay "evergreen" while the past 
discussion would not be 
as available to new members (or existing members who don't feel like searching 
archives)  Wiki 
pages are  also more easily referred to in response to new questions than an 
old discussion 
thread.

but if you are using server includes, you cannot do this-adding a strong 
tag to a specific link in the include. That's why many developers take 
the other approach. Additionally, the bottom (footer) links can be a 
"top level" category, where additional pages (3rd or deeper levels) fall 
under that category or section.

I'm just adding to the conversation as to WHY someone might take the 
other approach. With includes, you cannot make them different on each 
page, except via some overriding (specificity) unique combination of 
selectors, often started with the body tag and applying a class or id to it.

Just to throw in another thought on this - there are many times that you 
might have page functions that display or don't display, yet are part of 
an include. AND, you might be also setting the "selected" state of main 
and footer links (even utility type links)... in many cases, I find I 
have to go with classes *because* I can use more than one class, where I 
cannot use more than one ID on the body tag.

Well, that is only partly true, as you _can_ use variables in SSI, too
and highlight according to those. It is a bit messy though.
If you use PHP for example it is really easy to highlight the current
page and add a class to the parent links in a nested list:
http://www.onlinetools.org/tools/easynav/

I wrote this to actually allow users of contribute to edit the
navigation as an own HTML document and get the functionality.
If the bottom link points to the same location it should not have a
link either, if it doesn't there is no issue... If they are "top level
links" then I normally tend to nest a strong inside those links
instead of highlighting via a CSS class. In the css you can actually
distinguish via descendant selectors:

li strong {}
li li strong {}
li li li strong {}

Yes but using an idadequate technology should never be an excuse for
bad usability. You don't normally use windows paint to create your
website graphics either, and nobody complains that photoshop of
fireworks is not free or too expensive.
If your server does not support modern scripting technology, then you
might want to maintain the site locally, create static HTML pages from
templates with the unique navigation and FTP the lot over.

Visually, that does the trick, however not every user agent supports
CSS, and why should I get a bunch of links or even content that I
shouldn't get just because the server the site maintainer chose (or
was forced to use) does not support technology that has been around
for quite a while now - and is free?

All this extra content also adds to pageweight, which can be quite significant.

The visitors are those who bring either yourself or the client
money/fame/fun in the end, you don't create sites for yourself or for
the client to use.

There still can be a good reason to specify the element: human 
readability.  If it isn't otherwise obvious to someone maintaining 
the site a year later (or to someone helping someone else on a list 
like this one) that the unique #foo is actually a link, having a#foo 
in the CSS can help in figuring out what the identified item is 
supposed to be doing.  My understanding is that specifying the 
element does add fractionally to rendering time in at least one 
browsing engine, but in my view that consideration is generally 
outweighed by the ease-of-use for future development.

In any case, this particular issue is largely a matter of choice, and 
either way is not clearly better than the other.  Personally, I use 
both methods from time to time, depending on the particular context.
