Google Maps iFrame - Unwanted Blue Border

CodePen: https://codepen.io/Smgy94/pen/wvOjGyz?editors=0100 Hey Guys, I want to remove the blue border from the Goolge Maps iFrame when a user clicks on it or else change it to a different colour. Is this possible ? I've tried to use C to target the iframe and use border / outline :focus-within etc but I can't get rid of that blue line. Any helps appreciated! Cheers.
