HTML stands for Hypertext Markup Language. The first layer of any web cake helps create structured sections, headings, paragraphs, blockquotes, and links for web pages and applications. It builds the bones of any webpage, which ultimately forms a skeleton of that web page.
HTML is not a programming language. Therefore, you cannot define any logic by using that language.
A web structure consists of pages like home, about us, services, etc. HTML is used to create this web structure.
Note: To be an expert in front-end development, you must grasp these three languages: HTML, CSS, and JavaScript.
