Hello readers, Today in this blog you'll learn how to Create a Quiz Application with Timer using HTML CSS & JavaScript. Earlier I've shared a blog on how to Create a Responsive Personal Portfolio Website and now it's time to create Quiz Web App using JavaScript.
In this program [Quiz App with Timer], there are three layers or boxes, and these boxes shown one by one on a particular button clicked. At first, on the webpage, there is shown a button labeled as "Start Quiz" and when you clicked on that button, then the info box appears with popup animation. In this infobox, there are some rules of the quiz and two buttons labeled as "Exit" and "Continue". When you clicked on the Exit button, the info box will be hidden but when you clicked on the Continue button, then the Quiz Box appears.
In the Quiz Box, there is a header with a title on the left side and a timer box on the right side. This timer starts decrement from 15 to 0 sec and there is also shown a timeline indicator that is sliding from the left to right side according to the timer. If the user selects an option between 15 to 0 sec, the timer will be stopped and all available options will be disabled. If the user selected option is correct, the selected option color, background color changed to green and there is also shown the tick icon to inform the user that the selected answer is correct. If the user selects an option that is incorrect, the selected option color, background-color changed to red and there is shown the cross icon to inform the user that the selected option is incorrect and the correct option will be automatically selected.
If the user doesn't select an option between 15 to 0 sec, the timer will be stopped once it comes in 0 and the correct option of that question will be selected automatically. After that, there is the next button to show the next question, and there is a total of five questions on this Quiz. In the end, the result box will be appeared and shown the user score and two buttons [Replay Quiz, Quit Quiz], if the user clicked on the replay quiz button, the quiz will again start with the number 1 question, and the score of the user will be 0 but if the user clicked on the quit quiz button, the current window will be reloaded and the quiz starts from the begin.
You can copy the codes from the given boxes or download the code files from the given link but I recommend you to download the source code files instead of copying codes. Click here to download code files.
