Hi Anthony,
Thanks for posting in.
What device you’re testing it on? The screen size is small, but the screenshot is big (bigger that my screen). That gap is due to text on the right area. And attached is the screenshot I’m getting on my screen.
Image can’t respond on width and height at the same time. If you try to fit the height, then the width will increase affecting the content on both sides. You may want to set your image as background.
Thanks!
