Format trademark, registered trademark, service mark, and copyright symbols

Determine the appearance of the symbols created using the <tm> element as well as the copyright symbol.

Using the <tm> element along with the appropriate tmtype attribute value, you can create service mark (℠), registered trademark (®), and trademark (™) symbols. By default, those symbols are output superscripted above and smaller than the associated text. If you’d prefer to output them inline, that’s an easy change to make, although it’s not completely straightforward.

Tip: You can’t use <tm> to create a copyright symbol (©). For that, you either need to use the literal character or the numeric character reference (&#169; or &#x00A9;, for instance).
