Fixed, Auto, and Relative Position

In the hero section where it shows services. I have the background picture stay as you scroll up. I would like the button to move as you scroll up or down with it is currently position at. I believe it is the position of auto but now 100%. Here is the direct link to the mock up site for assistance.

Do you want your background image to be fixed when you scroll down ? If yes it is super simple, select your background image and click fixed.
If you want your button to be fixed when you scroll down, select your button and put position : fixed.

I didn’t explain it well. I want to have the button fixed. Say exactly where it is currently on the page as your scroll up or down.
