ADE 4 -and also ADE 2.x and ADE 3.x- with epub2 ebooks support the following properties (css2):
However, these properties when are used in an epub3 ebook, don't work. Why? I don't understand why ADE 4.x doesn't support them in epub3 and supports them in epub2. Also, don't work either (in epub3):
Many thanks in advance for any information about this issue.
