Writing Correct HTML Code

Admin February 21, 2025

 

Writing HTML is like baking a cake—follow the recipe correctly, and you'll have a delicious (or functional) result. Bad HTML, on the other hand, is like a cake that collapses in the oven. Let's ensure your web pages rise perfectly!

Best Practices for Writing Clean HTML

Follow these golden rules to keep your HTML professional, structured, and SEO-friendly.

1. Always Declare <!DOCTYPE html>

This declaration tells the browser that you’re writing in modern HTML5.

<!DOCTYPE html>
<html lang="en">

2. Properly Nest Your Tags

HTML tags should open and close in the correct order, like well-stacked LEGO bricks.

<p><strong>Correct:</strong> This is <em>properly nested</em>.</p>

3. Use Semantic HTML

Browsers and search engines love clear structure. Instead of using <div> for everything, use:

<header>, <nav>, <section>, <article>, <aside>, <footer>

Example:

<header>
    <h1>Welcome to My Website</h1>
</header>

4. Close Your Tags Properly

Unclosed tags = broken layout. Always close your tags properly.

<!-- Wrong -->
<p>Oops, I forgot to close my tag

<!-- Correct -->
<p>Nice, everything is in order!</p>

5. Use alt Text for Images

SEO loves alt text. It makes your site accessible and helps search engines understand images.

<img src="cat.jpg" alt="A cute cat enjoying the sun">

6. Keep Your Code Indented and Organized

Indentation helps readability. Compare these two:

<!-- Bad Formatting -->
<div><p>Hello</p><p>World</p></div>

<!-- Good Formatting -->
<div>
    <p>Hello</p>
    <p>World</p>
</div>

7. Optimize Loading Speed with Minimized Code

Use minified CSS and JavaScript files, optimize images, and avoid unnecessary elements.

<!-- Good -->
<link rel="stylesheet" href="styles.min.css">

8. Avoid Inline CSS and JavaScript

Keep your HTML clean by using external stylesheets and scripts.

<!-- Bad -->
<p style="color: red;">Hello!</p>

<!-- Good -->
<link rel="stylesheet" href="styles.css">

SEO Optimization Tips for HTML

Want search engines to love your site? Follow these tips:

  1. Use meta descriptions – These appear in search results and should be catchy.
<meta name="description" content="Learn how to write clean and optimized HTML code.">
  1. Use heading tags properly (h1 to h6) – Helps structure content for SEO and readability.
  2. Use meaningful URLs in href attributes – Clean, descriptive URLs rank better.
  3. Optimize for mobile – Use responsive design and the <meta viewport> tag.
<meta name="viewport" content="width=device-width, initial-scale=1.0">

Fun HTML Facts

  1. <blink> and <marquee> were cool in the 90s but are now as outdated as floppy disks.
  2. The <body bgcolor="red"> attribute used to exist before CSS took over.
  3. The alt text field can contain jokes—just in case search engines want a laugh.

Conclusion

Writing correct HTML is both an art and a science. Stick to best practices, optimize for SEO, and keep your code clean. Your website will be more accessible, faster, and rank higher in search results.

Now go forth and write HTML like a pro!
