Step-by-Step Guide to Building the Website
1. Setting Up the Structure with HTML
We’ll start with a simple layout that includes a form for URL input and a section for displaying results.
HTML Code:
htmlCopy code<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta name="description" content="Learn how to create a Page Speed Checker Website using HTML, CSS, and JavaScript. Free source code included.">
<meta name="keywords" content="Page Speed Checker, HTML CSS JavaScript, Website Performance, Free Code">
<meta name="author" content="Your Name">
<title>Page Speed Checker</title>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<header>
<h1>Page Speed Checker</h1>
<p>Analyze your website’s speed and performance instantly!</p>
</header>
<main>
<!-- Input Form -->
<section id="input-section">
<h2>Check Your Website Speed</h2>
<form id="speed-check-form">
<label for="url-input">Enter Website URL:</label>
<input type="url" id="url-input" placeholder="https://example.com" required>
<button type="submit">Check Speed</button>
</form>
</section>
<!-- Results Section -->
<section id="results-section" style="display: none;">
<h2>Performance Metrics</h2>
<div id="results"></div>
</section>
</main>
<footer>

</footer>
<script src="script.js"></script>
</body>
</html>
2. Styling the Website with CSS
Use CSS to create a clean and responsive design for the website.
CSS Code:
cssCopy codebody {
font-family: Arial, sans-serif;
margin: 0;
padding: 0;
background: #f4f4f9;
color: #333;
}
header {
text-align: center;
background: #4CAF50;
color: white;
padding: 20px;
}
main {
max-width: 800px;
margin: 20px auto;
padding: 20px;
background: white;
border-radius: 10px;
box-shadow: 0 2px 10px rgba(0, 0, 0, 0.1);
}
form {
display: flex;
flex-direction: column;
gap: 10px;
}
input[type="url"] {
padding: 10px;
border: 1px solid #ccc;
border-radius: 5px;
}
button {
padding: 10px;
background: #4CAF50;
color: white;
border: none;
border-radius: 5px;
cursor: pointer;
}
button:hover {
background: #45a049;
}
#results {
margin-top: 20px;
padding: 10px;
background: #f9f9f9;
border: 1px solid #ddd;
border-radius: 5px;
}
footer {
text-align: center;
padding: 10px;
background: #333;
color: white;
}
3. Adding Functionality with JavaScript
We’ll use JavaScript to handle URL input, fetch page speed data, and display the results.
JavaScript Code:
javascriptCopy codedocument.getElementById('speed-check-form').addEventListener('submit', async function (e) {
e.preventDefault();
const url = document.getElementById('url-input').value;
if (!url) {
alert('Please enter a valid URL!');
return;
}
// Display loading message
const resultsSection = document.getElementById('results-section');
const resultsDiv = document.getElementById('results');
resultsSection.style.display = 'block';
resultsDiv.innerHTML = '<p>Loading...</p>';
try {
// Example API integration (use a real API in production)
const response = await fetch(`https://api.example.com/speed-check?url=${encodeURIComponent(url)}`);
const data = await response.json();
// Display the results
resultsDiv.innerHTML = `
<h3>Results for: ${url}</h3>
<p><strong>Load Time:</strong> ${data.loadTime} seconds</p>
<p><strong>Performance Score:</strong> ${data.performanceScore}/100</p>
<p><strong>Recommendations:</strong> ${data.recommendations.join(', ')}</p>
`;
} catch (error) {
resultsDiv.innerHTML = `<p>Error fetching data. Please try again later.</p>`;
}
});
