Are you planning to create a Quiz App using HTML, CSS and JavaScript? In this article, We create a Quiz App using HTML, CSS, And JavaScript. In this JavaScript Quiz Project, we Score System and Previous and Next Question and After Quiz Done we can check right answer.
Quiz App Using HTML CSS and JavaScript
The main purpose of making a Quiz app in HTML CSS JavaScript is to make javascript concepts clearer and give users access to a web app so they may practice for competitive exams and improve their general knowledge. We’ll build a quiz app in this article.
Before we dive into the step-by-step process of creating a quiz app, let’s understand some of the general concepts of JavaScript for creating quiz apps.

});First, we built an object in our Javascript, and then we added a question with a certain ID number to that object. We have built 25 questions in total and placed them within our object. The user will receive the quiz task’s outcome at the end of the quiz by utilizing the conditional statements to verify, as the user clicks on any of the alternatives, if and else statements, whether the answer they choose matches the proper response.
