SiteOrigin Hero Button positioning

Hi

I am having a problem with positioning buttons on the hero widget. I am placing three hero widgets side by sidebar need the button to appear right at the bottom of the images on the left. I can’t seem to get the button to set bottom left, it always appears about mid way.

I am also having probs with the image sizing for the box. I really want three images to site side by side the same size with CTA button on each one. I am running full width.

I am confused as to what size I need the images to be either in the frame or the background to make them all the same size. Can you advise.
