Design an online quiz with questions from a domain of your choice. The questions should be chosen from a coherant domain, not just randomly chosen. Use creativity when choosing the domain.
Quiz questions should be multiple choice, chosen with radio buttons.
Your quiz should include at least five questions.
Provide hints for the questions if the quiz taker requests them. Display and hide the hints using the JavaScript style display property.
Obtain the correct answers from a JSON string. If you are up to the challenge (for extra credit), load everything from a JSON string, including the questions, hints, answers, and correct answer for each question.
Use images something like this to indicate whether a question is incorrect or correct:
Red and Green Checkmarks
Decide if the correct answers are shown after each question is answered, or if they are shown all at once after all the answers are entered and the quiz is submitted. Show a total score for the quiz after all answers are submitted.
