On Windows Mobile 8.1 devices like Nokia Lumia 1320, if the "Cookie notice" feature is activated the blue area comes out of the screen and it becomes impossible to click on the "Got it!" button.

I suggest this solution (source):

OPEN: 

./assets/cookieconsent/cookieconsent.min.css

FIND:

.cc-window.cc-floating{max-width:none}

REPLACE WITH:

.cc-window.cc-floating{max-width:100%}
