What is Introduction to HTML?
Within Computer Science, which covers algorithms, programming, data, networks, hardware and safe, responsible use of technology, this topic explains Introduction to HTML. Computing topics explain how software, hardware and data work, with diagrams and models that show each step in order.
Check that you can explain Introduction to HTML in your own words and give one example from everyday life. If you can do that, you have understood the core idea.
Understanding Introduction to HTML helps you design, test and explain programs, websites and systems, from small projects to exam questions.
Introduction to HTML in detail
HTML (HyperText Markup Language) is the standard language for structuring web pages. It uses tags in angle brackets, usually in pairs (<p>…</p>), to mark up content as headings (<h1>–<h6>), paragraphs, links (<a href="…">), images (<img src="…">), lists and tables.
A page has a <head>, with the title and metadata, and a <body>, with the visible content. Attributes give extra information to tags. HTML describes structure and meaning, not appearance (which is CSS) or behaviour (JavaScript). Semantic tags like <header>, <nav> and <footer> improve accessibility and search results. Browsers read HTML to display pages.
