Slider Button and Title Text Background

Where in the Customizr code is the position of the Slider Button set? And where is the color/opacity of the background screen for the Title Text set?

I would like to have the button appear lower on the image (75% down from top of image, rather than 50%) — and I’d like to remove the background screen (grey box) behind the Title Text completely.

Thanks for your help. I love the theme.
