Button positioning
Hi guys im currently in need of moving a button that im using to in between the bottom left of the screen and the bottom center of the screen, currently ive just added a left: 30% property to my place-self: end start css but its messy as when the screen shifts it doesn't always hit the same spot, anyone have any ideas on how i can get this positioning easier?
