Script for putting content on top of all pages
Hello. It's hard to explain but I want to know if there is a script or even an html code to put something on top of the web page and it not going away even if you change pages (withing the same site). For example, putting a box with a message in the corner of the page, and it staying there even when changing pages.
I can show what I mean with a music player. The music player here installs that way, and it doesn't move, disappear or load again even if you change pages within the website. I want to know if there is an specific script for that.
