Display different or extra content during the night time hours.
So it's evening time for your visitor. Is there something you'd like to show them that is more relevant at night? The stack will allow you to add or swap out content to be displayed to your visitor at night.
If you know a little CSS, you can get really creative, by applying a whole new look to your page at night. Simply add your CSS that should kick in at night time.
Note, you have total control of the hours that are considered "night time".
