You can use this Quiz App in Blogger, just paste the entire Source Code into a new page section or into new blog and your Quiz App Using JavaScript is ready to rock.

  1. HTML Section

    Utilizing all of the necessary elements and attributes is necessary before we can use HTML to establish the Quiz App Using JavaScript project's structure. This HTML Part will be our first step in creating the Calculator Section. In the future, we will be able to code the CSS to add styling and modify the labels. The HTML code can be found below; paste it where you want to use it by copying it.
  2. <!doctype html>
    <html lang="en">
        <!-- Required meta tags -->
        <meta charset="utf-8">

    <div class="score-container hide">
        <div id="user-score">Demo Score</div>
        <button id="restart">Restart</button>
  3. CSS Section

    Second, we have the styled CSS code for the Quiz App Using JavaScript project's structure. Additionally, the CSS code has been positioned and aligned in such a way that it does not become overloaded with the appropriate CSS elements. Now, let's program the CSS component to be responsive. Simply copy the code and paste it where you want to use it.

  5. JavaScript Section

    The final and most crucial phase of the project is JavaScript, where we added the logic and coded it in accordance with the Quiz App project's requirements, subject to a few conditions. We have also created functions that store responses and display them when the user gives an answer. Let's look at the Quiz App Using JavaScript's final step.
