Re: [oXygen-user] Differences in CSS counters between Author and Web Author

5 Oct 2018

      Hello,

If you change the CSS from

chapter > title:before {
    counter-reset: figure sect1_count;
}

to

chapter {
    counter-reset: figure sect1_count;
}

The difference between Author and Web Author is the handling of 
pseudo-elements. In Author :before is considered sibling with the 
element while in Web Author it is a child. This stackoverflow answer [1] 
helped me troubleshooting this problem, more precisely, these quotes 
from the CSS specification:

The scope of a counter starts at the first element in the document that 
has a 'counter-reset' for that counter and includes the element's 
descendants and its following siblings with their descendants.

If 'counter-increment' or 'content' on an element or pseudo-element 
refers to a counter that is not in the scope of any 'counter-reset', 
implementations should behave as though a 'counter-reset' had reset the 
counter to 0 on that element or pseudo-element.

Best,
Cristian

Hi,
I'm creating customized CSS stylesheet for DocBook based vocabulary. In
Author I need to prepend Figure X.Y label before each figure title.
Where X is chapter number and Y is number of figure inside chapter.
I'm doing this by providing additional styleheet in framework that is
extending DocBook framework:
figure > title:before {
   content: "Figure " counter(chapter_count) "." counter(figure) " ";
}
figure {
   counter-increment: figure;
}
chapter > title:before {
    counter-reset: figure sect1_count;
}
This works as expected in desktop Author. However in Web Author figure
number is being reset for each section, so for example for document like
<chapter>
   ...
   <section>
     ...
     <figure>  <!-- 1.1 -->
     ...
   </section>
   <section>
     ...
     <figure>  <!-- 1.2 -->
     ...
   </section>
</chapter>
Web Author labels both figures as 1.1.
I have briefly looked into HTML/CSS code of Web Author and it seems that
you are somehow preprocessing Author CSS stylesheet for browser and this
particular case is not handled properly.
I suppose there is no easy workaround for this, but perhaps next version
of Web Author could fix this ;-)
Many thanks and have a nice day,
Jirka
