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.

<strong>my bold content</strong>

my bold content

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.
