Writing clean HTML is an art. Here are the top best practices for formatting HTML code in professional environments.
1. Use Consistent Indentation
Whether you choose tabs or spaces, pick one and stick to it throughout the entire project. Inconsistent indentation makes code nearly impossible to read.
2. Keep Lines Under 80-120 Characters
Avoid extremely long lines of code. Break long elements with many attributes onto multiple lines for better readability.
3. Format Block Elements
Always place block-level elements (like <div> and <p>) on new lines. Never cram them onto a single line.
4. Use Meaningful Semantic Tags
Clean formatting is useless if your tags don't make sense. Use semantic HTML5 elements like <header> and <main> instead of endless divs.
