HTML is called Hypertext Markup Language, and most web pages are written in HTML code. HTML allows developers to determine exactly how multimedia, text, and hyperlinks are displayed in a web browser. In HTML, tags are used to define text structure; tags and elements are defined using the character, and the browser is primarily responsible for rendering web content through these tags. But over time, tags used to define document styles have almost been deprecated, as we have begun to prefer style sheets to add richness to web pages, and only content definition tags still form the core HTML.
