Is it possible to control the Lightbox behaviour?
I'd like to be able to change the background opacity and also zoom the lightbox in. Is this possible? I've searched the forum but can't find anything related.
By the way, I can't seem to change the background colour in the 'Thank You Message' editor. Whatever colour I pick it still defaults to a white background. I'm trying to match the grey colour of the form theme I'm using. I've tried emptying the cache. Any ideas?
However, you can still customize your form within form builder, so that you will be able to see that customized form in your lightbox.
As far as I can see, you have found solution for table background on your Thank You Page. You can also check this thread to find alternative solution with <div>.
