How to hide the Info Box for unregistered users?

There is a box “Welcome to OpenStreetMap! OpenStreetMap is a map…” appearing in the top left corner, blocking the view on a big part of the map. How do I hide it as an unregistered user? I use a desktop PC.

There’s an X, but made hard to see by the text :smiley:

I better get some glasses:cool:. Thank you!
