That is exactly what I'm talking about and it gives me a great basis
for trying to articulate what is confusing me.
I am apparently under the mistaken impression that when we insert into
an HTML document Ruby code that is included within <% %> like this:
<% ruby code %>
the inserted Ruby code is run at the point where it is inserted into
the HTML document. When that Ruby code completes, any HTML code that
follows is sent to the requesting browser. The point is that at any
given time either Ruby code is being run or HTML is being sent to the
requesting browser. What your Ruby code does is interact with a
segment of HTML code so that that segment of HTML code is sent to the
browser conditionally. That just blows my mind. How are we able to
accomplish that? Or, is that just something that I should accept and
try not to think about too much? I would think that if we were going
to include content conditionally, that content would have to be within
the <% %> and quoted. My concern is that I am missing some very
important point about <% %> that, if I weren't missing it, my
understanding would be a whole lot better.

Yes. I understand what content_for does. I was just using it to
provide an example of the type of thing that I was talking about.
Thanks to all for the input.
