Title: How to Build a Simple Quiz App with a Timer Using HTML, CSS, and JavaScript?

In this tutorial, we will create a simple Quiz Application with Timer using HTML, CSS, and JavaScript. This step-by-step guide aims to provide you with a strong foundation and a practical example to kickstart your journey in developing similar interactive applications. By the end of this tutorial, you'll have a functional quiz app with a countdown timer to enhance user engagement.

What Does the Quiz Application with Timer Do?

The Simple Quiz Application with Timer is a user-friendly and interactive tool designed to test knowledge with a time-bound challenge. This application presents users with a quiz containing 5 multiple-choice questions. Users must complete the quiz within a time limit of 2 minutes and 30 seconds. If the timer runs out, the application automatically displays the results, even if some questions are left unanswered.

As users select their answers, the application instantly checks their response. Correct answers are highlighted with a green background, while incorrect choices are marked with a red background. This immediate feedback enhances the learning experience, making the quiz engaging and informative.

Let's start the coding part!

Step 1: Creating a JSON File

First, let's create a new JSON file. This file will store the data for the quiz questions that will be presented to the users. The JSON structure consists of objects with the following keys:

  • id: A unique identifier for each question.
  • question: The text of the question to be displayed.
  • choices: An array of possible answers.
  • answer: The correct answer, represented by the index of the correct choice in the choices array.

Below is an example of a JSON data structure created for this tutorial to define the quiz questions and answers:

data.json

  1. [
  2.     {
  3.         "id": 1,
  4.         "question": "Which of the following is a JavaScript framework?",
  5.         "choices": ["Django", "React", "Flask", "Ruby"],
  6.         "answer": 1
  7.     },
  8.     {
  9.         "id": 2,
  10.         "question": "What does HTML stand for?",
  11.         "choices": ["Hyper Text Markup Language", "High Transfer Markup Language", "Hyperlinks and Text Markup Language", "Hyper Transfer Machine Language"],
  12.         "answer": 0
  13.     },
  14.     {
  15.         "id": 3,
  16.         "question": "Which of the following is used to declare a variable in Python?",
  17.         "choices": ["var", "let", "def", "None of the above"],
  18.         "answer": 3
  19.     },
  20.     {
  21.         "id": 4,
  22.         "question": "What is the output of console.log(typeof null) in JavaScript?",
  23.         "choices": ["null", "undefined", "object", "string"],
  24.         "answer": 2
  25.     },
  26.     {
  27.         "id": 5,
  28.         "question": "Which of these is not a valid CSS property?",
  29.         "choices": ["color", "font-size", "text-align", "print-mode"],
  30.         "answer": 3
  31.     }
  32. ]

Step 2: Creating the Interface

Next, let's create the HTML file for our Quiz Application. This file will contain the essential elements for the application's structure, such as the header, timer, and placeholders for questions and choices. Note that the actual questions and choices will be dynamically generated and are not included directly in this file. Below is an example of the HTML code created for this tutorial:

index.html

  1. <!DOCTYPE html>
  2. <html lang="en">
  4.     <meta charset="UTF-8">
  5.     <meta name="viewport" content="width=device-width, initial-scale=1.0">
  6.     <title>Quiz App with Timer</title>
  7.     <link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=Material+Symbols+Outlined:opsz,wght,FILL,[email protected],100..700,0..1,-50..200" />
  8.     <link rel="stylesheet" href="style.css">
  9.     <script src="https://code.jquery.com/jquery-3.7.1.min.js"></script>
  10. </head>
  12.     <div id="main-wrapper">
  13.         <div id="app-title">Quiz App with Timer using HTML, CSS, and JavaScript</div>
  14.         <div class="flex-container align-center justify-center w-100">
  15.             <button id="start-button" type="button"><span class="material-symbols-outlined">contract_edit</span> Start Quiz</button>
  16.         </div>
  17.  
  18.         <div id="quiz-container">
  19.             <div class="flex-container align-center justify-between w-100">
  20.                 <div class="flex-grow-1">

  22.                     <span id="current_question_number"></span>
  23.                     <span>&nbsp;out of&nbsp;</span>
  24.                     <span id="total_question_number"></span>
  25.                 </div>
  26.                 <div id="timer-container" class="flex-container align-center justify-center">
  27.                     <span class="material-symbols-outlined">timer</span>
  28.                     <span id="timer">00:00</span>
  29.                 </div>
  30.             </div>
  31.             <hr class="hr-light">
  32.             <div id="quiz-list"></div>
  33.             <div id="quiz-actions" class="flex-container w-100 align-center justify-end">
  34.                 <button id="prev-question-btn" class="quiz-action-btn" type="button"><span class="material-symbols-outlined">chevron_left</span> Prev</button>
  35.                 <button id="next-question-btn" class="quiz-action-btn" type="button"><span class="material-symbols-outlined">chevron_right</span> Next</button>
  36.                 <button id="finish-question-btn" class="quiz-action-btn" type="button"><span class="material-symbols-outlined">check_small</span> Finish</button>
  37.             </div>
  38.         </div>
  39.  
  40.         <div id="quiz-result">
  41.             <div id="quiz-result-text">
  42.             </div>
  43.             <div class="flex-container align-center justify-center w-100">
  44.                 <button id="restart-button" type="button"><span class="material-symbols-outlined">contract_edit</span> Restart Quiz</button>
  45.             </div>
  46.         </div>
  47.     </div>
  48.     <script src="script.js"></script>
  49. </body>
  50. </html>

Step 3: Designing the Interface

Now, let's create the custom Cascading Stylesheet (CSS) for our application. This file defines the visual design and layout of the application's elements, ensuring a user-friendly and visually appealing interface. Below is the CSS code crafted for this tutorial:

style.css

  1. @import url('https://fonts.googleapis.com/css2?family=Ubuntu:ital,wght@0,300;0,400;0,500;0,700;1,300;1,400;1,500;1,700&display=swap');
  2.

  236.     text-align: center;
  237.     margin: 20px 0;
  238. }

Step 4: Creating the Main Functions

Finally, let's create the JavaScript file. This file contains the essential JavaScript code that powers the functionality of the Quiz Application with Timer. The JavaScript manages features like loading questions, validating answers, keeping track of the timer, and displaying results. To make the code more efficient and easier to write, I have also utilized jQuery. Below is the JavaScript code for your reference:

script.js

  1. // Quiz Start Button
  2. const StartBtn = $('#start-button')
  3. // Quiz Restart Button
  4. const RestartBtn = $('#restart-button')
  5. // Quiz Questionnaire Container
  6. const Questionnaire = $('#quiz-container')
  7. // Quiz List Container
  8. const QuizList = $("#quiz-list")
  9. // Quiz Item Element to Clone
  10. const QuizItem = $(`
  11. <div class="quiz-item">
  12. <div class="quiz-item-question">Lorem ipsum dolor sit amet, consectetur adipiscing elit</div>
  13. <div class="quiz-item-choices">
  14. </div>
  15. </div>
  16. `)
  17. const QuizChoiceEL = $(`
  18. <a href="javascript:void(0)" class="quiz-choice">Choice 101</a>
  19. `)
  20. // Previous Button
  21. const PrevBtn = $('#prev-question-btn')
  22. // Next Button
  23. const NextBtn = $('#next-question-btn')
  24. // Finish Button
  25. const FinishBtn = $('#finish-question-btn')
  26. // Current Question Number
  27. const CurrentQNumber = $('#current_question_number')
  28. // Total Question Number
  29. const TotalQNumber = $('#total_question_number')
  30. // Result Container
  31. const ResultContainer = $('#quiz-result')
  32. // Result Text
  33. const ResultText = $('#quiz-result-text')
  34.  
  35. // Timer Element
  36. const timerEL = $('#timer')
  37. var questions = [];
  38. var currentQindex = 0;
  39. var timerSec = 150;
  40. var score = 0;
  41. var answerArr = [];
  42.  
  43. var TimerInterval;
  44.  
  45. // Load JSON Data
  46. async function fetch_data() {
  47.     return await fetch("data.json")
  48.         .then(response => {
  49.             if (!response.ok) {
  50.                 console.error(response);
  51.             }
  52.             return response.json();
  53.         })
  54.         .then(data => {
  55.             return (data)
  56.         })
  57.         .catch(error => {
  58.             console.log(error)
  59.         })
  60. }
  61.  
  62. function shuffle(arrData) {
  63.     let curIndx = arrData.length;
  64.     while (curIndx != 0) {
  65.         let randIndx = Math.floor(Math.random() * curIndx);
  66.         curIndx--;
  67.  
  68.         [arrData[curIndx], arrData[randIndx]] = [
  69.             arrData[randIndx], arrData[curIndx]];
  70.     }
  71. }
  72.  
  73. function check_ans(el){
  74.     el.find(".quiz-choice").click(function(e){

  113.                 if(answerArr[i].wrong > 0)
  114.                     el.find(`.quiz-choice[data-key="${answerArr[i].wrong}"]`).addClass("wrong");
  115.                 el.find(`.quiz-choice`).addClass("disabled")
  116.             }
  117.         }
  118.     }
  119. }
  120.  
  121. // Computing and Updating Timer
  122. function computeTimer(time){
  123.     var min = Math.floor(time / 60) | 0;
  124.     var sec = Math.ceil(time - (min * 60));
