Thanks very much for all the suggestions!
I ended up tweaking the CSS to remove the requirement, and using with WYMeditor to gain more control of the internal markup, including the addition of classes, although I’m still exploring that aspect.
Curious though, Carlo and John, you both indicate that I can use a custom field to set the class. I’ve tried this - sort of - but ee adds it’s own containing tags, which are not accessible (as far as I can tell), and only visible when HTML is sent to the browser. What I end up with is nested tags, which messes up my formatting.
It looks like I’m still missing something, so could you describe the method I should use to access, and target, the inaccessible container tags generated by ee on XHTML fields?
Thanks very much!
