Looking for a way to disable buttons (answers) in a quiz game after an answer is chosen

Solution for Looking for a way to disable buttons (answers) in a quiz game after an answer is chosen
is Given Below:

I am looking for a way to disable buttons (answers) in a quiz game after an answer is chosen.
I am also looking for a way to disable the counter from being incremented after an answer is chosen.
One more problem is I tried linking fontawesome.com and other sites to use a simple icon and I only get empty squares for some reason.

I have no idea why I am unable to use disable property !! HELP U.U

Hue is a degree on the color wheel from 0 to 360. 0 is red, 120 is green, 240 is blue.
Saturation is a percentage value; 0% means a shade of gray and 100% is the full color.
Lightness is also a percentage; 0% is black, 100% is white.
correct syntax hsl(h, s%, l%)

we use hue to have more control over all color attributes separately

  1. All the lines that set the disabled property are commented out with “//”.

  2. All the lines that set the disabled property try to load element “btn”, but the ID string needs to match the actual element you want to disable, e.g. “start-btn”.

  3. To change behavior such as disabling a counter, wrap the code that increments the counter in an if (ShouldCount) { [code that increments here] } condition. Have ShouldCount start true and set it to false when something happens that you want to stop the counter, and true when something happens that you want to restart the counter.

  4. I don’t know what you’re trying to do with FontAwesome, but you should ask individual questions, not all your questions in one question.
