You can already place content on a page and change how it looks. Today you will build an interactive quiz game for the web with HTML, CSS and JavaScript.

You will set up a CodePen project, show questions and answer buttons, check each choice, keep a score, and finish by writing five quiz questions of your own on a subject you choose.

Before you run anything, look at the first build step and think: what do you expect to see on the page when the starter structure is in place?

First, open CodePen by visiting https://codepen.io and create a new project.

CodePen: How to create a new project

---

To create a new project or 'pen' in CodePen, open the website codepen.io and:

1. Click the 'Start Coding' button
2. This will create a new project (or 'pen') and bring you to online editor.

In this step, we will add the HTML structure for our Interactive Quiz Game. Add the following HTML code to the HTML section of your CodePen:

<h1>Interactive Quiz Game</h1>
<div id='quiz'></div>
<div id='result'></div>
<div id='score'></div>

Here's a brief explanation of each element:

• <h1>Interactive Quiz Game</h1>: This is the main heading of our quiz game.
• <div id='quiz'></div>: This div will contain the questions and answer options for our quiz.
• <div id='result'></div>: This div will display the result of the user's answer, whether it's correct or incorrect.
• <div id='score'></div>: This div will show the user's score when they complete the quiz.

Now let's add some styling to our HTML elements to make them look better.

Add the following CSS code to the CSS section of your CodePen:

body {
  font-family: Arial, sans-serif;
  background-color: #f0f0f0;
  padding: 20px;
}

h1 {
  text-align: center;
}

#quiz {
  background-color: #fff;
  padding: 20px;
  border-radius: 5px;
}

.answer {
  display: block;
  margin: 20px auto;
  background-color: #007bff;
  border: none;
  color: #fff;
  padding: 10px 20px;
  border-radius: 5px;
  cursor: pointer;
}

.answer:hover {
  background-color: #0056b3;
}

#result, #score {
  text-align: center;
  font-size: 24px;
  font-weight: bold;
}
