HTML-based websites are primarily constructed using Hypertext Markup Language (HTML) as the primary markup language for structuring content and layout. HTML-based sites rely on HTML tags to define elements such as headings, paragraphs, images, links, and other page components. These sites are uncomplicated and lightweight, as they do not require intricate server-side scripting or integration with databases. They are suitable for designing simple informational websites, personal blogs, or static web pages that do not demand frequent updates or dynamic content. HTML-based websites are easy to maintain, load swiftly, and are compatible with a broad range of web browsers and devices. While HTML-based websites may lack sophisticated functionality and interactivity when compared to dynamic sites, they remain a popular option for those looking for a basic online presence or a platform to begin web development.
