Love calculators have become quite popular on the internet, allowing users to determine their compatibility with their partners or crushes.

Step-by-step Love Calculator Using HTML, CSS, and JavaScript

In this tutorial, we will guide you on how to create a love calculator using HTML, CSS, and JavaScript. The love calculator will take the names of two individuals and calculate a love percentage based on a simple algorithm.

Step:1 HTML Structure

Let’s start by creating the basic HTML structure for our love calculator:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Love Calculator</title>
    <link rel="stylesheet" href="style.css">
</head>
<body>
    <h1>Love Calculator</h1>
    <div class="love-calculator-container">
  <form id="love-calculatorForm">
    <label for="love-calc_yourName">Your Name:</label>
    <input type="text" id="love-calc_yourName" required>

    <label for="love-calc_partnerName">Partner/lover/crush's Name:</label>
    <input type="text" id="love-calc_partnerName" required>

    <button class="love-calc_button" type="button" onclick="calculateCompatibility()">Calculate</button>
  </form>

  <div id="love-calc_result"></div>
</div>

<div class="love-calc-container">
  <p><span id="love-calc_result__string"></span></p>
  <p><span id="love-calc_result__numstr"></span></p>
  <div id="love-calc_result__rescontent">
    <img src="/image/love-compatibility-calculator.png" height="396px" width="396px"
      alt="Love Compatibility Calculator" title="Love Compatibility Calculator">
    <p class="love-calc_message"></p>
  </div>
</div>

    <script src="script.js"></script>
</body>
</html>

In the above code, we have created a simple HTML form with two input fields for entering the names of the two individuals. We have also added a submit button and a div element with an id of “love-calc_result” where the love percentage will be displayed.

HTML Structure Explanation:

In this HTML code, we’ve structured a Love Compatibility Calculator using a container with various elements for user interaction and result display.

1. Love Calculator form container: <div class="love-calculator-container">
  • <div class="love-calculator-container">: This is the main container for the entire Love Calculator section.
    • <h2>Love Compatibility Calculator</h2>: Displays a heading for the Love Calculator.
    • <form id="love-calculatorForm">: This form contains input fields for the user to enter their name and their partner’s name.
      • <label for="love-calc_yourName">Your Name:</label>: Label for the input field where the user enters their name.
      • <input type="text" id="love-calc_yourName" required>: Text input for the user’s name.
      • <label for="love-calc_partnerName">Partner/lover/crush's Name:</label>: Label for the input field where the user enters their partner’s name.
      • <input type="text" id="love-calc_partnerName" required>: Text input for the partner’s name.
      • <button class="love-calc_button" type="button" onclick="calculateCompatibility()">Calculate</button>: A button that triggers the calculateCompatibility function when clicked.
    • <div id="love-calc_result"></div>: An empty div where the result of the love compatibility calculation will be displayed.

The provided HTML code represents the structure of the result container in the Love Compatibility Calculator. Let’s break down the elements within the <div class="love-calc-container">:

2. Result Text: <div class="love-calc-container">
<p><span id="love-calc_result__string"></span></p>

This creates a paragraph (<p>) element containing a <span> with the ID love-calc_result__string. The content of this span will be dynamically updated using JavaScript to display a personalized message about the love compatibility.

Result Percentage:
<p><span id="love-calc_result__numstr"></span></p>

Similar to the first paragraph, this creates another paragraph with a <span> having the ID love-calc_result__numstr. This span will be dynamically updated to display the calculated love compatibility percentage.

Result Content:
<div id="love-calc_result__rescontent">
  <img src="/image/love-compatibility-calculator.png" height="396px" width="396px"
    alt="Love Compatibility Calculator" title="Love Compatibility Calculator">
  <p class="love-calc_message"></p>
</div>

This div (<div>) contains two elements:

  1. Image: <img src="/image/love-compatibility-calculator.png" height="396px" width="396px" alt="Love Compatibility Calculator" title="Love Compatibility Calculator">
    • An image element displaying a Love Compatibility Calculator illustration. The source (src) is set to “/image/love-compatibility-calculator.png”, and attributes like height, width, alt text, and title are provided.
  2. Message Paragraph: <p class="love-calc_message"></p>
    • An empty paragraph element with a class of “love-calc_message”. This paragraph will be dynamically populated with a message about the love compatibility based on the calculated percentage.
Overall:

This structure encapsulates the visual representation of the Love Compatibility Calculator result. When the compatibility is calculated, JavaScript will update the content of the spans and paragraphs to provide a personalized message along with the love compatibility percentage. The image serves as an illustrative element, enhancing the visual appeal of the result container.

Step:2 CSS Styling

Great! Now, let’s add some CSS styling to make our Love Calculator look more appealing. I’ll provide a basic example, but you can customize it further according to your preferences:

/* style.css */

/* Add this CSS to your stylesheet or in a <style> tag in the head of your HTML document */

body {
  font-family: 'Arial', sans-serif;
  background-color: #f5f5f5;
  margin: 0;
  padding: 0;
}

.love-calculator-container {
  max-width: 600px;
  margin: 50px auto;
  background-color: #fff;
  padding: 20px;
  border-radius: 8px;
  box-shadow: 0 0 10px rgba(0, 0, 0, 0.1);
}

h2 {
  color: #333;
  text-align: center;
}

form {
  margin-top: 20px;
}

label {
  display: block;
  margin-bottom: 8px;
}

input {
  width: 100%;
  padding: 8px;
  margin-bottom: 16px;
  box-sizing: border-box;
}

.love-calc_button {
  background-color: #4caf50;
  color: #fff;
  border: none;
  padding: 10px 15px;
  cursor: pointer;
  border-radius: 4px;
}

.love-calc_button:hover {
  background-color: #45a049;
}

#love-calc_result {
  display: none;
  margin-top: 20px;
}

.love-calc-container {
  margin-top: 30px;
}

#love-calc_result__string,
#love-calc_result__numstr {
  text-align: center;
}

#love-calc_result__numstr h5 {
  color: #4caf50;
}

.love-calc_message {
  margin-top: 20px;
}

.love-calc_message h6 {
  color: #333;
}

.love-calc_message p {
  color: #555;
  line-height: 1.6;
}

In the above CSS code, we have defined styles for the body, heading, form, labels, input fields, submit button, and result div.

Step:3 JavaScript Logic

Now let’s add the JavaScript logic to calculate the love percentage based on the names entered:


function calculateCompatibility() {
  const yourName = document.getElementById("love-calc_yourName").value;
  const partnerName = document.getElementById("love-calc_partnerName").value;

  // Calculate compatibility using ASCII values sum
  const yourNameScore = calculateNameScore(yourName);
  const partnerNameScore = calculateNameScore(partnerName);

  // Normalize scores to be between 0 and 100
  const compatibilityScore = Math.floor(
    (yourNameScore + partnerNameScore) % 101
  );

  // Display the result
  const resultStringContainer = document.getElementById("love-calc_result__string");
  const resultNumStrContainer = document.getElementById("love-calc_result__numstr");
  const resultMessageContainer = document.querySelector(".love-calc_message");

  resultStringContainer.innerHTML = `<h4>${yourName} loves ${partnerName}</h4>`;
  resultNumStrContainer.innerHTML = `<h5 style="color: red;">${compatibilityScore}%</h5>`;

  if (compatibilityScore <= 49) {
    // Low Compatibility
    resultMessageContainer.innerHTML = `<h6>Low Compatibility</h6>
				<p><strong>Both of you have nothing in common and may find it tough to maintain a healthy and lasting relationship.</strong></p>
				<p>Your differences may pose significant challenges, making it difficult to find common ground. While relationships thrive on diversity, it's important to assess whether fundamental incompatibilities hinder the potential for a lasting connection. Honest communication and self-reflection are essential in navigating this journey.</p>
				<p>Consider whether your individual goals, values, and interests align. While differences can be enriching, a balance must be struck to ensure a healthy relationship. If maintaining common ground proves challenging, it may be necessary to evaluate the compatibility of your long-term goals and whether they align for a fulfilling and lasting partnership.</p>`;
  } else if (compatibilityScore <= 69) {
    // Neutral Compatibility
    resultMessageContainer.innerHTML = `<h6>Neutral Compatibility</h6>
				<p><strong>Both of you share a few common interests and have to put in a lot of effort. But, with open communication, you may overcome the differences and build a lasting bond.</strong></p>
				<p>Your journey together may require extra effort and understanding, as you navigate through areas where your interests differ. Open communication is key to bridging the gaps and building a lasting connection. With patience, empathy, and a willingness to compromise, you can forge a bond that strengthens over time.</p>
				<p>Recognize the unique qualities that each of you brings to the relationship. As you navigate through life's challenges, focus on finding common ground and building a foundation of trust. By fostering open and honest communication, you can overcome obstacles and create a lasting bond that grows stronger with every shared experience.</p>`;
  } else if (compatibilityScore <= 89) {
    // Moderate Compatibility
    resultMessageContainer.innerHTML = `<h6>Moderate Compatibility</h6>
				<p><strong>Both of you have a lot in common and may have a fulfilling relationship.</strong></p>
				<p>Your connection is built on shared interests and mutual understanding. While you may encounter challenges along the way, your common ground provides a solid foundation for a relationship filled with shared experiences and joy. Embrace your similarities, celebrate your differences, and work together to create a bond that stands the test of time.</p>
				<p>Communication and compromise are the pillars of your relationship. As you navigate through life's twists and turns, your ability to understand each other and find middle ground will be crucial. Remember to cherish the moments of laughter, support each other's dreams, and celebrate the uniqueness that each of you brings to the relationship.</p>`;
  } else {
    // High Compatibility
    resultMessageContainer.innerHTML = `<h6>High compatibility</h6>
				<p><strong>Both of you share a strong connection and cherish each other.</strong></p>
				<p>When you find "the one," everything else simply fades away. Your love and compatibility shine brightly enough to make the gods envious. From your shared passion for exotic cuisine and adventurous travel to the rhythm of your laughter and the joy of your unique hobbies, you mirror each other, drawing out the best of your individual personalities and fostering a bond that grows stronger with every passing day.</p>
				<p>While occasional disagreements may arise, they are mere ripples in the vast ocean of your love. Together, you navigate through challenges, finding solutions and emerging stronger, more united than ever. What you share is a truly precious gift, a love etched in the tapestry of fate. Nurture it with care, protect it with passion, and watch it blossom into a timeless masterpiece.</p>
				<p>Time may test the depths of your connection, throwing obstacles in your path, but remember, your love is an unwavering flame. Together, you will face every storm, hand in hand, and emerge victorious, your bond forged in the crucible of time.</p>`;
  }

  // Display the result container
  document.getElementById("love-calc_result").style.display = "block";
}

function calculateNameScore(name) {
  let score = 0;
  for (let i = 0; i < name.length; i++) {
    score += name.charCodeAt(i);
  }
  return score;
}

This JavaScript code is responsible for calculating the love compatibility percentage based on the names entered by the user and dynamically updating the result message accordingly.

  } else if (compatibilityScore <= 69) {
    // Neutral Compatibility
    resultMessageContainer.innerHTML = `<h6>Neutral Compatibility</h6>...`; // Message for neutral compatibility
  } else if (compatibilityScore <= 89) {
    // Moderate Compatibility
    resultMessageContainer.innerHTML = `<h6>Moderate Compatibility</h6>...`; // Message for moderate compatibility
  } else {
    // High Compatibility
    resultMessageContainer.innerHTML = `<h6>High Compatibility</h6>...`; // Message for high compatibility
  }
