Web Development - Random Quote Generator

This is a project that generates random quotes from wise people plus a game on checking the knowledge regardings these quotes. The technologies used were HTML, CSS and JS. So, without further ado let's dive right in.

First, let's see the main HTML source code.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

    <link rel="stylesheet" href="style.css">

<body>
    <div class="main-container">
        <div class="title">
            <img id="logo" style="width:100px;height:100px;" src="./logo/logo.png">
            <h2>Random Quote Generator</h2>
        </div>
        <!-- Display data -->
        <div class="quote-container">
            <p id="quote"></p>
        </div>
        <div class="person-container">
            <p id="person"></p>
        </div> 
        <div class="birthdate-container">
            <p id="birthdate"></p>
        </div> 
        <div class="dieddate-container">
            <p id="dieddate"></p>
        </div> 
        <div class="image-container">
            <img id="img" src="" />
        </div>
    </div>
    <!-- Buttons -->
    <div class="outer-container">
        <button title="🕵️ Press me to see what happens." id="mystery-button">Mystery Quote</button>
        <button title="🍀 Generate a random Quote!" id="generate-button">Generate</button>
        <button onclick="document.location='./game.html'" title="🎲 Game ON!" class="game-button">Game</button>
        <button title="🔄 Refreshes the page." id="reset-button">Reset</button>
        <p id="show-clicked"><b>This Button Clicked <span id="display">0</span> Times</b><b><span id="record"></span></b></p>
    </div>
    <div class="about-item">
        Created with ❤️ and Enthusiasm by <a href="https://github.com/mariosdaskalas" target="_blank"><span>@mariosdaskalas</span></a>
    </div>
</body>
<script src="main.js"></script>
</html>

At first, we create a bunch of divs to hold the generated information, that is the quote itself, who said the quote, the birth and death date. After that, we have several buttons, each with a different functionality.

The 'Mystery Quote' generates a random quote without revealing who said that quote. The 'Generate' button generates a quote with all the above information. The 'Game' button initiates a game that will see in the next section. Finally, the 'Reset' button just refreshes the page in order to start from the beginning.

Let's include the CSS as well. No need to explain it, pretty basic stuff.

body {
    background: rgb(74, 68, 190);
    font-family: Roboto;
    font-size: 98%;
}
.title {
    color: white;
    text-align: center;  
    height: 8.65em;
}
#logo {
    text-align: center;
}
.quote-container {
    background-color: #C4C4C4;
    text-align: center;
    font-size: 110%;
}
.person-container, .birthdate-container, .dieddate-container {
    background-color: #C4C4C4;
    text-align: center;
    font-size: 110%;
    margin-top: 0%;
}
#mystery-button, #generate-button, .game-button, #reset-button, #back-button, #start-game-button, #possible-answer, #submit-button, #results-button{
    margin-top: 1%;
    border: none;
    color: black;
    padding: 15px 32px;
    text-align: center;
    text-decoration: none;
    display: inline-block;
    font-size: 16px;
    cursor: pointer;
}
.outer-container {
    text-align: center;
}
#img {
    display: block;
    margin: auto;
    width: 100%;
    max-width: 460px;
    height: auto;
}
#show-clicked {
    color: white;
}
#person10, #person20 {
    color: white;
    font-size: 120%;
}
#correct, #false, #question {
    color: white;
    font-size: 110%;
}
#totalQuotes {
    color: white;
}
#show-results {
    color: white;
    font-size: 110%;
    visibility: hidden;
}
.about-item {
    text-align: center;
    background-color: #C4C4C4;
    width: 50%;
    margin: 0 auto;
}
a, a:visited {
    color: black;
}
a:hover {
    font-weight: bold;
}

Now let's see the game itself which is a HTML and a JS file.

<!DOCTYPE html>

    <div class="main-container">
        <div class="title">
            <img id="logo" style="width:100px;height:100px;" src="./logo/logo.png">
            <h2>Random Quote Generator</h2>
        </div>
        <div class="quote-container">

        </div>
        <div class="person-container">

        </div>
    </div>
    <div class="outer-container">
        <!-- Select choice -->
        <div class="person-container-answer">
            <form>
                <input type="radio" name="choice" id="person1" checked>

                <input type="radio" name="choice" id="person2">
                <label id="person20" for="person2"></label>
            </form> 
        </div>
        <!-- Buttons -->
        <button title="🏠 Go to Homepage." onclick="document.location='./index.html'" id="back-button">Back</button>
        <button title="🔄 Refreshes the page." id="reset-button">Reset</button>
        <button title="🏃‍♂️ Starts the game." id="start-game-button">Start</button>
        <button title="📝 Submit your answer." id="submit-button">Submit</button>
        <button title="📈 See Results." id="results-button">Results</button>
        <p id="correct"></p>
        <p id="false"></p>
        <p id="question"></p>
        <p id="totalQuotes"><b>You have answered <span id="display">0</span> Quotes so far.</b></p>
        <p id=show-results>Results: Correct: <span id="correctResults"></span> - Wrong: <span id="wrongResults"></span></p>
    </div>
    <div class="about-item">
        Created with ❤️ and Enthusiasm by <a href="https://github.com/mariosdaskalas" target="_blank"><span>@mariosdaskalas</span></a>
    </div>
</body>
<script src="game.js"></script>
</html>

At first, we create a container that holds the quote and which person said that quote. You get to choose between two options. You select an option and if you are correct, you get 1 point, otherwise nothing. There is an option to display the final results if you want to.

Finally, the JS of the game.

// Store quotes and other data

};

// Create array with values from 0 till quotes length
let arr = [];
for (let i = 0; i <= Object.keys(quotes).length - 1; i++) {
    arr.push(i);
}

        return n != random;

    /*

    or on second radio button
    the choices

    */
    if (randomButton == 0) {
        document.getElementById("person1").value = randomName;
        document.getElementById("person10").innerHTML = randomName;
        console.log(`The name ${randomName} index is ${random}.`);

function submitAnswer() {

        document.getElementById("false").style.visibility = "hidden";
        document.getElementById("correct").style.visibility = "visible";
        countCorrect++;
    }
    else if (p2 == true && cp2 == randomName) {
        console.log("Correct Answer.");
        document.getElementById("correct").innerHTML = "✔️ Correct Answer"
        document.getElementById("false").style.visibility = "hidden";
        document.getElementById("correct").style.visibility = "visible";
        countCorrect++;
    }   
    else {
        console.log("False Answer.");
        document.getElementById("false").innerHTML = "❌ False Answer.";
        document.getElementById("false").style.visibility = "visible";
        document.getElementById("correct").style.visibility = "hidden";
        countFalse++;
    } 
}
    document.getElementById("results-button").addEventListener("click", showResults);
    let resultsButton = document.getElementById("results-button");

    // Display how many correct/false answers you had
    function showResults() {
        document.getElementById("show-results").style.visibility = "visible";
        console.log(`Correct: ${countCorrect}`);
        console.log(`False: ${countFalse}`);
        correctResults.innerHTML = countCorrect;
        wrongResults.innerHTML = countFalse;
    }

In the beginning, we have an object that holds a series of arrays. Inside a for loop, we push to an empty array the integer values from 0 till the length of the object.

Afterward, we generate a random quote using Math.random() and display that on the screen. We store the value of the button and check it against the supplied answer. If the answer is correct, we increase the count++ by one, which is used later as a variable for storing the scores.
