I have objections about styling, much better approach than distracting visitors with read more button, is linking Privacy policy in text. Of course it is really easy to modify, but still I don't like it:
- notice text should certainly be aligned left not center
- text should also not take whole screen width, but leave space near the edge for a button
- button ought to be on the right side of the screen, to the right of notice text
Also I don't like to be forced to set expiry, while I already have it configured in details in my htaccess file. I am not even sure which setting has a priority now. What about option "defined elsewhere"?
