Thanks for reply. I added your css code to make the window smaller and also this outline: 9999px solid rgba(0,0,0,0.5); and now the overlay under the window is gray :-)
Hi,
Thanks for your answer. We use Piwik and not Google Analytics. This function is very important for us. So I’d like to ask, if you are able to develop this for us and how much that it would cost.
