The quiz interface is divided into sections: a title area and a timer section. The timer counts down from 15 seconds, accompanied by a visual indicator moving across the screen to give a sense of time passing.
Users need to select an answer within this 15-second window. Once they choose, the timer stops, and they can’t change their selection. This prevents any last-minute alterations after the time is up, ensuring fairness.
When users pick the correct answer, their choice lights up in a bright green color, and a checkmark symbol appears to confirm their correctness. If they select the wrong answer, their choice turns red, and a cross icon appears. Simultaneously, the correct answer becomes visible, providing immediate feedback.
If users don’t make a selection within the time limit, the timer hits zero, stops, and automatically marks the correct answer for that question.
The interface offers a “Next” button to navigate through a total of five questions.
Once the quiz concludes, a score display appears. Users have two choices: they can replay the quiz, starting again from question one with their score reset, or they can choose to quit, resetting the quiz entirely and starting from scratch.

CSS :
This CSS code styles a quiz application webpage. It sets a Google Font for text, defines a general style for the entire page, and includes specific styles for the start, information, quiz, and result sections. It incorporates transitions for smooth animations and responsiveness. Colors, fonts, and layouts contribute to a cohesive design, enhancing the user experience.

JavaScript File 1 (for questions) :
This JavaScript code defines an array named questions
containing multiple objects. Each object represents a quiz question and includes properties such as numb
(question number), question
(the actual question), answer
(correct answer), and options
(an array of answer options). Users can add or remove questions by uncommenting or duplicating the provided template, ensuring the numb
values are in sequential order.
// creating an array and passing the number, questions, options, and answers let questions = [ { numb: 1, question: "What does HTML stand for?", answer: "Hyper Text Markup Language", options: [ "Hyper Text Preprocessor", "Hyper Text Markup Language", "Hyper Text Multiple Language", "Hyper Tool Multi Language" ] }, { numb: 2, question: "What does CSS stand for?", answer: "Cascading Style Sheet", options: [ "Common Style Sheet", "Colorful Style Sheet", "Computer Style Sheet", "Cascading Style Sheet" ] }, { numb: 3, question: "What does PHP stand for?", answer: "Hypertext Preprocessor", options: [ "Hypertext Preprocessor", "Hypertext Programming", "Hypertext Preprogramming", "Hometext Preprocessor" ] }, { numb: 4, question: "What does SQL stand for?", answer: "Structured Query Language", options: [ "Stylish Question Language", "Stylesheet Query Language", "Statement Question Language", "Structured Query Language" ] }, { numb: 5, question: "What does XML stand for?", answer: "eXtensible Markup Language", options: [ "eXtensible Markup Language", "eXecutable Multiple Language", "eXTra Multi-Program Language", "eXamine Multiple Language" ] }, // you can uncomment the below codes and make duplicate as more as you want to add question // but remember you need to give the numb value serialize like 1,2,3,5,6,7,8,9..... // { // numb: 6, // question: "Your Question is Here", // answer: "Correct answer of the question is here", // options: [ // "Option 1", // "option 2", // "option 3", // "option 4" // ] // }, ];
JavaScript File 2 (for script) :
This JavaScript code controls the logic and functionality of a quiz application. It handles the start, continuation, and completion of the quiz, as well as user interactions with questions and options. Key elements include timers for each question, tracking the user’s score, and displaying the results.
Additionally, it dynamically updates the user interface based on user actions and the state of the quiz. The code employs event listeners and functions to manage the flow of the quiz application.
