Re: Designations in docbook for conversion to ePub

Hi Philo,

Regarding your first question, if you put a role attribute on a phrase (<phrase role=“red”>contents</phrase>), the value of that role will be carried to the HTML (e.g., <span class=“red”>contents</span>)

You can then apply css normally.

Regarding your second question, I’m not so sure what’s the best thing to do, but you might try the same approach, wrapping the inlinemediaobject in a phrase with a role, then key off whatever sequence of spans you get (probably something like span.XYZ>span.inlinemediaobject>img).

I hope that helps.

To be error free, I need to specify with width  through a CSS designation like img.half where img.half is set to 50% width in the CSS. Is there a way in Oxygen XML to specify a designation in docbook that will at least tag these images so that I can add the CSS specification for width?
