Is there a solution available for changing the background color in HTML when a specific button is pressed, like the letter A? I want the color to switch from red to green or green to red when button A is pressed, and I would like it to stay that way even if I am not focused on the web browser. Apologies for the basic question and any language barriers. Thank you in advance for any responses.
I found a link similar to what I am looking for, but it changes the background color based on a button click: how to change different background colors using only one button
