Hey all,

Is it possible to add a controller.php or form.php to a container, like a custom block?  
I would like some more flexibility on how the container looks when added on a page.  
Like changing:

- background-color
- background-image
- padding-top
- …

This would make it much more easier than it is implemented right now. If i would like to use the same container, on the same page (or another page, doesn’t matter) but this time with a background-image. I would have to hardcode this per container.

This could quickly result in a few dozen containers each with its own style.

So is this already a possibility? Or will this be a new feature?

Cheers,  
Darryl

+1 for this - the ability to add classes would be even more powerful and dramatically cut down on the number of containers needed.
