👉 HTML (HyperText Markup Language) is the foundational language for creating and structuring web pages. It uses a set of tags and attributes to define elements like headings, paragraphs, links, images, and forms, allowing developers to build the basic structure and layout of a website. While HTML itself is relatively simple, effective engineering involves organizing elements semantically to enhance accessibility and SEO, using CSS for styling, and leveraging JavaScript for dynamic interactions. Proper HTML engineering ensures that web pages are not only visually appealing but also functional, accessible, and maintainable, forming the backbone of any digital content delivery system.
