Note:

 [b] ) has two uses. In this exact form, with no trailing space and no content,  [b] ) , it is used within  [style] ) and  [gstyle] ) to place the entire block of content fed to the style. To learn more about this, see the  [style] ) built-in.

The second form, which is distinguished by having content, is the HTML bold built-in. That is what is described on this page.

Note: The class instantiation parameter semantic defaults to True. This causes  [b content] ) to emit  <strong>  and  </strong> ; if you prefer  <b>  and  </b> , set semantic to False.
