Introduced in December 1997, HTML 4 aimed to enhance the functionality and flexibility of web pages while addressing some of the limitations of its predecessors. This article explores HTML 4 in detail, covering its key features, impact on web development, and its legacy.
Introduction to HTML 4
HTML 4, formally known as HTML 4.01, was a major update to the HTML standard. Developed by the World Wide Web Consortium (W3C), HTML 4 introduced a range of new features and improvements that revolutionized web development. It emphasized the separation of content from presentation, supported more advanced multimedia elements, and improved scripting capabilities. This version of HTML set the stage for the rich, interactive web experiences we enjoy today.

Key Features of HTML 4
HTML 4 brought several notable enhancements over its predecessors. Here are some of the key features introduced with HTML 4:
1. Separation of Content and Presentation
One of the most important changes in HTML 4 was the emphasis on separating content from presentation. This was achieved through the use of Cascading Style Sheets (CSS). By moving styling information to external CSS files, HTML 4 allowed developers to create more consistent and maintainable designs across multiple web pages.
