Banner on mobile not displaying correctly

I have Dawn theme. My homepage banner on desktop doesn’t fit on mobile. Can someone help. Www.coventryfireworksking.co.uk

  1. How do we ensure the banner resizes automatically on mobile view so the sides aren’t cut off and only centre section of the banner shows. Need to make it mobile compatible.

  2. What are the actual dimensions for a banner on our theme that is compatible with all views - desktop/mobile/full screen

@CovFK

@media screen and (max-width: 600px) {
     banner__media media .media>img {
      object-fit: fill !important;
  }
}

Add this css at the bottom of Online Store->Theme->Edit code->Assets->base.css

Hi

Do you mean this?

(max-width: 600px) { .media>img { object-fit: fill !important; } }

@CovFK
