Hey Ismael,
the page is open accessible now. The plugin I use, is the “flowfact-wp-connector”. My problem is the dark background on the overview page and, that when you choose one of the elements, it shows with dark grey writing on black ground an I find no way to change that.
Hopefully you have a solution so that I don’t have to change the theme.

Best regards, Jo Achim

Hi Rikard,
no, it’s a different page, http://www.englitz-immobilien-hannover.de/immobilienbewertung-fuer-optimalen-verkaufserfolg, which is going to be a landing page. Password in private content. What I would like to achieve, is, that the whole page background (bleeding to the very edges) is in #215ba8, which is the company color. All content I want to put in transparent boxes so that white text lies on the blue background. I have found numerous hints, but nothing works right.

Best Regards
Jo Achim
