Why Follow Best Practices?
Following HTML best practices ensures your code is clean, maintainable, accessible, and optimized for performance and SEO.
Use Semantic HTML
Use semantic elements like <header>, <nav>, <main>, and <footer> instead of generic <div> tags for better structure and accessibility.
Keep Code Clean and Indented
Always Close Tags Properly
Ensure all tags are properly opened and closed to avoid rendering issues.
Use Lowercase Tags and Attributes
HTML is case-insensitive, but using lowercase improves readability and consistency.
Add Alt Text for Images
Use External CSS and JS
Separate structure (HTML), styling (CSS), and behavior (JavaScript) for better maintainability.
Optimize Meta Tags
Avoid Inline Styles
Use CSS instead of inline styles to keep HTML clean.
