I would like to customize the newsletter pop-up both on desktop and mobile beyond what the theme editor is allowing… here are the edits I am hoping to make:

  1. Make desktop pop-up text area less wide & taller and image to take up 50% of the pop-up instead of how it is now. Image attached is inspo for sizing:

  1. MOBILE ONLY: Have background be an image entirely with an overlay opacity of 25%, attaching inspo below:

Any help in achieving these would be so appreciated, thank you!
