1. Elements and Tags: HTML consists of a wide range of elements, each serving a specific purpose. Elements define the different parts of a webpage, like headings, paragraphs, images, lists, tables, forms, and more. Tags are used to represent these elements, and they are the fundamental building blocks of HTML documents.
2. Nesting and Hierarchy: HTML elements can be nested inside other elements, creating a hierarchical structure for organizing content. Proper nesting is crucial to ensure that the web page displays as intended and follows web standards.
3. Compatibility and Cross-Browser Support: HTML is designed to be platform-independent and works across different web browsers and devices. However, browsers may interpret HTML slightly differently, so web developers must ensure their code is cross-browser compatible.
4. HTML is often used in conjunction with other technologies, particularly Cascading Style Sheets (CSS) for styling and JavaScript for adding interactivity and dynamic behavior to web pages. Together, HTML, CSS, and JavaScript form the core technologies of front-end web development, allowing developers to create visually appealing and interactive web experiences.
