Edited by Aimie Carlson || By Harlon Moss || Published on February 9, 2024
HTML 4 is an older web standard with basic functionality, while HTML 5 introduces advanced features like multimedia support, semantic elements, and improved interactivity.
Key Differences
HTML 4, a standard released in 1997, focused on the structure and presentation of content on the web. HTML 5, introduced in 2014, expanded these capabilities, incorporating multimedia, graphic content, and better semantic understanding.
In HTML 4, multimedia elements like video and audio required third-party plugins. HTML 5, however, has built-in support for audio and video, making multimedia integration seamless and more accessible.
HTML 4’s design limitations often required extensive use of JavaScript and CSS to create dynamic websites. HTML 5 addresses these limitations by introducing new elements and APIs for enhanced functionality and interactivity.
HTML 4 lacked support for mobile devices, a significant limitation in today’s mobile-first world. HTML 5 offers mobile-friendly features, making it adaptable and responsive to various screen sizes and devices.
