Let’s break it down part by part:

HTML Structure:

External Resources:

Loads external CSS files for styling and icons from different CDNs (Content Delivery Networks).
Imports JavaScript file(s).

Page Structure:

Divides the body into sections for the start button, information box, quiz box, and result box.
Displays different sections like the rules, questions, timer, options, and buttons.

CSS Styling:

The CSS styling is not included in the provided code, but it would typically contain the styles for the various elements in the HTML.

JavaScript Functionality:

Event Handling:
- Handles button click events (Start, Exit, Continue, Next, Replay, Exit Quiz).
- Controls the visibility of different sections by adding or removing CSS classes.
Quiz Logic:
- Manages the quiz questions, options, and answers.
- Controls the countdown timer for answering each question (starts from 10 seconds).
- Randomizes option placement for each question.
- Evaluates user-selected answers and updates the score.
- Displays result box with the user’s score based on the number of correct answers.
- Implements restrictions, such as not allowing backward navigation after selecting an answer, not allowing an answer selection after the timer expires, and not allowing quiz exit while playing.
Additional UI Interactions:
- Visual feedback for correct and incorrect answers (icons and animations).
- Vibration effect on a wrong answer (for mobile devices).
Functions:
- showQuestions(index): Displays questions and options based on the index.
- startTimer(time): Manages the countdown timer functionality.
- startTimeLine(time): Controls the visual timeline indicating the time limit.
- showResultBox(): Displays the final result of the quiz.
- queCount(index): Updates the question count.
- optionSelected(answer): Handles the selection of an option, checks correctness, updates the score, and manages UI elements accordingly.

Overall Functionality:

When the Start Quiz button is clicked, it shows the rules of the quiz. Upon Continue, it starts the quiz, displaying questions one by one with a time limit.
The user goes through the quiz, answering questions, and can see the final result at the end.

This example creates a simple quiz app with a couple of questions. The questions and their choices are stored in an array in JavaScript. The app displays questions, allows the user to select an answer, and keeps track of the score.

You can expand this further by adding more questions, implementing a timer, adding levels, or even integrating a backend to store user scores. This is just a basic structure to get you started.
