OK Sergey full marks for the banner at the top but how about this for a suggestion?
The cookie warning popup is well annoying on sites but I have a friend that runs a what looks like responsive website which has implemented the dialog slightly differently rather than a modal popup they have used a tab in the bottom left corner (as seen on desktop)
Think its nice and I wish more sites would use something similar.
