Image is not resizing as screen size hanges

Hi,

Can you fix the image on the notification bar as the screen size change to tablet and mobile?

On desktop it fits perfectly. But as the screen changes to tablet and mobile screen, the image size stays the same and it aligns vertically to the top leaving a small gap below it. See attached. Can it fit perfectly using custom css please. There’s currently a custom css applied and please keep it as is. And just fox the issue.

Thanks in advance you are very helpful.
