HTML 4 vs. HTML 5 — What's the Difference?

Difference Between HTML 4 and HTML 5


Key Differences

HTML 4, introduced in 1997, focused on the structure and presentation of content on the web. HTML 5, released in 2014, brought significant advancements, emphasizing web applications' compatibility and multimedia handling capabilities.
In HTML 4, multimedia elements like video and audio required third-party plugins and software, such as Adobe Flash. HTML 5 introduced native support for audio and video elements, eliminating the need for external plugins.
HTML 5 supports advanced web technologies such as offline web application storage, drag-and-drop, and canvas drawing. HTML 4 did not have these capabilities, limiting the interactive features websites could offer.
HTML 5 also introduces form controls and attributes like placeholder, autofocus, and autocomplete, enhancing form interactivity and user experience. HTML 4's form capabilities were more basic, offering fewer options for validation and user interaction.
