Outline for image frame

I'm trying to add a line around my image which is currently set to "Fill" (not "Fit") so the outline needs to be around the images frame. Any help would be greatly appreciated

@Martian can you share this page URL? Also what would you like the border to look like?

@CassAggett Just a thin 1 pixel line around the image frame (I'd love the option to change the color if that's possible

@Martian Give this code a go - paste in the Custom CSS panel:

#block-64bd83023798211dc839a7d4 .fluid-image-container.sqs-image-content { 
  border: 1px solid lightblue;
  box-sizing: border-box;
}

You can change where it says lightblue to another colour name or hex code.

Hopefully this will work as is to target just that image in the screenshot but if not let me know
