I have done everything as shown including browser zoom at 100% but still getting the wrong answer.
Try post your code and link to the challenge; so that we can have more context on the issue you are facing.
(Also a hard reload of the page sometimes fixes it, there are case where the browser simply “jams”)
The following is what I posted as directed, but still staying red and unable to move on.
Can you please post the whole code, that snippet is not enough to detect the issue
