Submit button not working in J S radio button quiz

The issues with the CSS styling may stem from incorrect syntax or missing styles that prevent the proper display of the tick mark and X.

Ensure that the CSS file is correctly linked in the HTML and that there are no conflicting styles that could override the desired appearance.

Using characters like 'a"' without proper encoding or using an incorrect character entity can cause rendering issues for tick marks and crosses.

Cross-browser compatibility should be checked since certain CSS properties may behave differently depending on the browser being used.
