title: VS Code transition:background-color not working
body: <p>In VS Code When I add &quot;transition : background-color&quot; it's not highlighted and not working either. The same error occurred to me when I was adding the animation. Can anyone please explain to me, why this is happening? I have included image links below.</p>
