Trademarks
Trademarks are used to specify legally registered words and they are often used in technical documentation. To specify a trademark, your DITA content could use a structure similar to this:
<tm tmtype="tm">My Product Name</tm>Depending on the value of the @tmtype attribute, a different symbol is
appended to the text: (®, ™ , or ℠).
The structure of the merged HTML document the CSS will apply to is:
<span class="- topic/tm tm" tmtype="tm">My Product Name<span
class="- topic/tmmark tmmark ">™</span></span>How to Style the Trademark Element Text
To change the style of the entire trademark text, you can match the
topic/tm class like this:
*[class ~= "topic/tm"] {
font-weight:bold;
}How to Style the Trademark Symbol
To change the aspect of the trademark symbol, you can use the
topic/tmmark class. Usually, common fonts already render these symbols
smaller and with superscript by default. The following example does it from the CSS:
*[class ~= "topic/tmmark"] {
vertical-align: super;
font-size: smaller;
}
