HTML 4.0 vs. HTML5
What's the Difference?
HTML 4.0 and HTML5 are both versions of the Hypertext Markup Language used for creating web pages, but they have some key differences. HTML 4.0 is an older version that was released in 1997 and has limited support for multimedia elements and interactive features. On the other hand, HTML5 is a more modern version that was released in 2014 and includes new features such as native support for video and audio, canvas elements for drawing graphics, and improved support for mobile devices. Overall, HTML5 offers more flexibility and functionality for web developers compared to HTML 4.0.

Further Detail
Introduction
HTML, which stands for HyperText Markup Language, is the standard markup language used to create web pages. Over the years, HTML has evolved to include new features and capabilities. HTML 4.0 was released in 1997, while HTML5 was introduced in 2014. In this article, we will compare the attributes of HTML 4.0 and HTML5 to understand the differences between the two versions.
Structure
One of the key differences between HTML 4.0 and HTML5 is the way they handle the structure of a web page. HTML 4.0 relies on a more rigid structure with specific tags for defining elements such as headers, paragraphs, and lists. In contrast, HTML5 introduces new semantic elements like
Media Support
Another significant improvement in HTML5 is its enhanced support for multimedia elements. HTML 4.0 required external plugins like Adobe Flash to display audio and video content on a web page. With HTML5, native support for audio and video tags allows developers to embed media directly into the page without the need for third-party plugins. This not only simplifies the development process but also improves the performance and accessibility of multimedia content.
Forms
HTML forms are an essential part of web development, allowing users to input data and interact with websites. HTML 4.0 forms were limited in terms of functionality and styling options. HTML5 introduces new input types like email, date, and range, as well as attributes like required and placeholder that enhance the usability and user experience of web forms. Additionally, HTML5 form validation features make it easier to validate user input without relying on JavaScript.
Canvas and SVG
HTML5 introduces two new elements,
Offline Support
One of the most significant advancements in HTML5 is its support for offline web applications. HTML5 introduces the Application Cache and Local Storage APIs, which allow web pages to store data locally and be accessed offline. This feature is particularly useful for mobile devices and areas with limited internet connectivity, as it enables users to access web content even when they are not connected to the internet.
Compatibility
When it comes to compatibility, HTML5 is designed to be backward compatible with older versions of HTML, including HTML 4.0. This means that web pages written in HTML 4.0 should still render correctly in modern browsers that support HTML5. However, some older browsers may not fully support all HTML5 features, requiring developers to use polyfills or fallbacks to ensure compatibility across different platforms.
Conclusion
In conclusion, HTML5 represents a significant advancement in web development compared to HTML 4.0. With its improved structure, multimedia support, form capabilities, graphics elements, offline features, and compatibility, HTML5 offers developers a more powerful and versatile tool for creating modern web applications. While HTML 4.0 laid the foundation for web development, HTML5 has taken it to the next level with its enhanced features and capabilities.
