I didn't see the point of adding the class to the html code because
it seemed to me that it could be identified without it, so I
experimented by leaving out the class and addressing it in the CSS
with just

#sweden dd img {float: left;}

and it seemed to work fine.  But I'm the beginner, and the expert
used the class.  I'm sure there was a reason; I just don't know what
it is.  Can anyone tell me why it's necessary or a good idea to add
that class to identify the image?

I don't see the point either - in that case. (I haven't read the book.)

However, if you have an image in one 'dd' you want to 'float', and an
image in another 'dd' that you _don't_ want to add that style to, then
the extra class on 'dd' can be used to separate them.

You may then of course just as well add a class to the image you want to
'float' itself, in such a mixed case.

Plenty of options available, and every site may need its own strategy
for use of these options. Test them out, and try to keep it simple and
understandable as you go along, as it will be much easier to maintain
later on. (I should have followed that rule myself :-) )
