HTML has evolved over time to support modern web development. HTML5 introduced many new features compared to older versions like HTML4 and XHTML.
HTML5 uses a much simpler doctype compared to older versions.
<!DOCTYPE html>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
HTML5 introduced semantic tags that clearly describe their purpose. Older HTML relied heavily on <div> tags.
| HTML5 | Older HTML |
|---|---|
| <header>, <footer>, <article>, <section> | <div> and <span> |
HTML5 provides native support for audio and video without external plugins.
<video controls>
<source src="video.mp4">
</video>
Older HTML versions required plugins like Flash for multimedia.
HTML5 introduced new input types and attributes for better validation.
HTML5 includes powerful APIs that were not available in older versions.
| Feature | HTML5 | Older HTML |
|---|---|---|
| Doctype | Simple | Complex |
| Semantic Tags | Available | Not available |
| Multimedia | Native support | Plugin-based |
| Form Controls | Advanced | Basic |
| APIs | Built-in | Not available |
HTML5 represents a major improvement over older HTML versions. It enables modern, accessible, and interactive web applications.
Using HTML5 ensures better performance, maintainability, and user experience.
