About
Hypertext Markup Language (HTML) is a markup language used to create web pages and is the de facto standard for documents displayed in web browsers.
It defines the structure of web content using elements for text, links, images, forms, tables, and embedded media, organizes documents into a hierarchical DOM, and enables hyperlinking between pages, which is a fundamental mechanism of the World Wide Web.
The Speculation Rules API is a browser API that improves navigation performance by prefetching or prerendering pages that users are likely to visit next.
It uses 
JSON-based rules embedded in 
HTML or HTTP headers, and is designed as a successor to older techniques such as 
Prefetch and the deprecated Prerender attribute.
