I need a little help

Hey Guys
my web designer has made something for me but it is not something i really liked.
Here is the link:

but this is something i have requested:
https://floris.menew.pw/

Avia tab is working ok but i need all content to be available without changing the tab. The tabs must work as a bookmark.

As the designer is not available right now, can you help me to edit the code?
I don’t have access to purchase code to enter the forum because the designer has purchased.

thanks.
