The HTML code sets up the basic structure of the webpage. It includes meta tags for SEO, schema.org markup for local business information, and CSS styling within the <head>. The <body> contains the main content, including a header, services section, contact information, and footer. Everything seems well-organized and semantic.

Potential HTML issues:

  • Duplicate HTML structure in JavaScript section: The provided Javascript code includes an entire HTML structure again. This is definitely wrong. Javascript code should only contain javascript. I will explain this more in the Javascript section.
  • Accessibility: While the structure is good, adding ARIA attributes could further improve accessibility, especially for users with disabilities.

  <script>
    // Hiệu ứng rung cho nút "Gọi ngay"
    const callBtn = document.getElementById('callNow');
    setInterval(() => {
      callBtn.style.transform = 'scale(1.1)';
      setTimeout(() => callBtn.style.transform = 'scale(1)', 150);
    }, 4000);

    // Hiển thị tình trạng mở cửa
    const openStatus = document.getElementById('openStatus');
    const now = new Date();
    const hour = now.getHours();
    if (hour >= 7 && hour <= 21) {
      openStatus.textContent = '⏰ Hiện tại: Đang mở cửa (7:00 - 21:00)';
    } else {
      openStatus.textContent = '🔒 Ngoài giờ làm việc (7:00 - 21:00)';
      openStatus.style.color = '#d32f2f';
    }
  </script>
</body>
</html>

The JavaScript code adds interactivity to the page.

  • Button Animation: It makes the "Gọi ngay" button pulsate using setInterval and CSS transforms. This helps draw attention to the call-to-action. Also, the scaling factor 1.1 for hovering the button is really good for UI.
  • Business Hours Display: It dynamically displays whether the business is currently open based on the current time. This is a helpful feature for users.

Potential Javascript issues:

  • Duplicate HTML structure: As I mentioned above, the provided Javascript code includes an entire HTML structure again. This is an incorrect way to write Javascript code. Javascript code should only contain javascript to make the HTML elements interactive. Copying HTML code in Javascript will not make the Javascript code work.
  • Use querySelector for better targeting: Instead of getElementById, consider using querySelector for more flexible element selection.
  • Consider using CSS animations: For the button animation, CSS animations might provide smoother performance and be easier to manage.

CSS Styling

:root {
  --accent: #d32f2f;
  --accent-dark: #b71c1c;
  --muted: #6b6b6b;
  --bg: #f7f7f7;
  --radius: 12px;
  --shadow: 0 6px 20px rgba(0, 0, 0, 0.06);
}

/* Reset */
* {
  box-sizing: border-box;
  margin: 0;
  padding: 0;
}

body {
  font-family: system-ui, -apple-system, 'Segoe UI', Roboto, 'Helvetica Neue', Arial;
  line-height: 1.6;
  color: #222;
  background: var(--bg);
}

/* Container chính */
.hero {
  max-width: 1000px;
  margin: 40px auto;
  padding: 28px;
  background: #fff;
  border-radius: var(--radius);
  box-shadow: var(--shadow);
  animation: fadeIn 0.6s ease-in-out;
}

@keyframes fadeIn {

The CSS defines the visual appearance of the website. It uses CSS variables (:root) for easy customization of colors, fonts, and spacing. The styling is clean and modern, with a focus on readability and a professional look.

Potential CSS issues:

  • Consider using a CSS preprocessor: Using Sass or Less could make the CSS more maintainable and organized, especially for larger projects.
  • Optimize for different screen sizes: Ensure the website is fully responsive and looks good on all devices.

General Recommendations

  • Validate HTML, CSS, and JavaScript: Use online validators to check for syntax errors and ensure code quality.
  • Optimize Images: Compress images to reduce file size and improve loading speed. This is crucial for user experience and SEO.
  • Test on Different Browsers and Devices: Ensure the website works correctly across various browsers (Chrome, Firefox, Safari, Edge) and devices (desktops, tablets, smartphones).
  • Implement Analytics: Use Google Analytics or similar tools to track website traffic and user behavior. This data can inform future improvements and marketing efforts.
  • Fix Duplicate HTML: The duplicate HTML within the JavaScript block needs to be removed. The JavaScript should only contain JavaScript code to manipulate the existing HTML elements.

Conclusion

Overall, the code for Giặt Ghế Sofa Hà Nội is well-structured and functional. Addressing the potential issues outlined above, such as the HTML duplication and Javascript issues, optimizing images, and improving accessibility, can significantly enhance the website's performance and user experience. By focusing on these areas, the website can achieve even greater success in attracting customers in Hanoi seeking professional sofa cleaning services. Remember, a clean website is just as important as a clean sofa!

I hope this analysis helps you out! Goodluck!
