Reply to: Custom CSS and PI’s: little big problemSeptember 12, 2012 at 8:07 pm
My assumption was correct. The type of selector you want to build that includes a PI isn't supported. You will need to find another way to uniquely identify the element in question.
If you can't build an alternate selector (possibly requiring you to add more markup to the XML) you might wish to look at styling the element using the Range.ContainerStyle API inside a script. Your script would need to find the element.
