Formatted XUL Tab caption

Question

Is there an easy way to have formatted tab captions in XUL? I want to have a specific part of the tab caption in bold font.

Answer 1

No easy way. XUL <tab>'s text is in a <label>, which doesn't give you fine-grained control over parts of the text. You'd have to replace it with a <description> which can contain HTML markup, but this is not a standard thing to do.

Answer 2

An easier way perhaps is to put multiple <label>'s inside the <tab> Eg :

<tabbox>
 <tabs>
  <tab>
   <label style="margin-right: 0px;" value="normal"/>
   <label style="margin-left: 0px; font-weight: bold;" value="bold"/>
  </tab>
 </tabs>
</tabbox>

Of course it depends on what it's used for exactly.
