hey guys today we are going to learn how to make a quiz app using HTML CSS and JavaScript. It’s a great project for everyone who wants to improve their coding skills in HTML, CSS & JavaScript. Inside the project you will learn how to use HTML & CSS to design the complete applications, then you will learn how to use JS to manipulate the elements.
Creating a quiz app from scratch can be a rewarding and educational experience, and you don’t need to be an expert coder to get started. In this article, we will guide you through the process of building a quiz app using three essential web technologies: HTML, CSS, and JavaScript. We will break down the steps in a simple and easy-to-follow manner, so even beginners can embark on this exciting journey.
A quiz app is a dynamic web application that allows users to answer a series of questions and receive immediate feedback on their performance. This type of app can be used for educational purposes, testing knowledge on various topics, or simply for fun. By the end of this tutorial, you’ll have the knowledge and confidence to create your own quiz app.
Quiz App Using HTML CSS and JavaScript
The first step in building a quiz app is to design its HTML structure. HTML (Hypertext Markup Language) is the backbone of web pages and will define the content and layout of our quiz app.
<div class="quiz-container" id="quiz">
<div class="quiz-header">
<h2 class="header-txt">Technology Quiz</h2>
</div>
<div class="quiz-body">
<h2 id="question">Question Text</h2>
<ul>
<li>
<input type="radio" name="answer" id="a" class="answer" />
<label for="a" id="a_text">Questions</label>
</li>
<li>
<input type="radio" name="answer" id="b" class="answer" />
<label for="b" id="b_text">Questions</label>
</li>
<li>
<input type="radio" name="answer" id="c" class="answer" />
<label for="c" id="c_text">Questions</label>
</li>
<li>
<input type="radio" name="answer" id="d" class="answer" />
<label for="d" id="d_text">Questions</label>
</li>
</ul>
</div>
<div class="quiz-footer">
<div class="quiz-details"></div>
<button type="button" id="btn">Submit</button>
</div>
</div>
Once you’ve set up the HTML structure, it’s time to make your quiz app visually appealing using CSS (Cascading Style Sheets). CSS controls the design and layout of your app, giving it a polished look.

The core of your quiz app lies in JavaScript. JavaScript will handle user interactions, display questions, track scores, and provide feedback.
