When you insert a registration mark (®) into your HTML, it comes in pretty much right in the vertical middle of the line. It looks weird there, as many a client has pointed out to me. They’d like to see it superscripted and I agree that’s where it looks most appropriate.

So you might try superscripting it (^®) but this presents another problem. It also inserts a little bit of extra space above the line that contains it, throwing off the line spacing if it’s tight.

How to have a nicely superscripted registration mark that doesn’t destroy the even spacing of text? Try this - works in FF, Netscape and Opera…

In your CSS file:

span.reg {
position: relative;
top: -3px;
font-size: 10px;
}

And in your (X)HTML:

®

Now in IE6 and 7, what I see when I implement this is that the mark looks fine until I touch the scrollbar - then it (and all the other marks with the same class) stays put on the page (like it’s fixed) while the rest of the content moves. It looks like IE6 and 7 don’t like ‘position: relative;’ in a span tag? I’m not sure. Looking for answers about this issue now.
