Ok, what I want is styling ANY container that I had created. Do you mean that there is not anyway to give an ID or CLASS to any given container created by shortcode?
This is a container created in WP Estate…
[container_content title="" border=""]
How can I give an ID or CLASS to it? Or where can we edit the shortcode container to add that feature? with the attribute border="" I can define border style and I need to be able to style or refer to any container. I can create a DIV inside the container but I don’t want that many nested DIVs.
