Responsive podcast access request landing page with JS form validation

I know it isn't perfect. I've brute-forced some of the positioning of things (hello dots and submit button). I'm also not super happy with how the gray logos look at different sizes.

Things I'd like to know: • How to make the SVG images in the logo grid appear the same size (when compared to each other) at all screen sizes. • How to get my submit button, that uses overlapping CSS grid techniques, to have just a little bit of margin on the right so the button appears to be completely contained in the input field. (it looks good everywhere but the right side)

Thanks everyone!
