📖 1. HTML Tags Structure

🔑 Key Concepts & Definitions

• HTML tags are the fundamental components used to create web pages, serving as the building blocks of content and structure.
• Angle brackets < > are used to enclose HTML tags, marking the beginning and end of each tag.
• Pairs of tags consist of an opening tag (e.g., <h1>) and a closing tag (e.g., </h1>), which together define the start and end of an element.
• Nesting refers to placing one HTML tag inside another, allowing complex and hierarchical webpage structures (e.g., <b><i>Text</i></b>).

📝 Essential Points

• Every HTML tag is wrapped in angle brackets <>, which distinguish tags from other content.
• Most HTML tags come in pairs: the opening tag initiates an element, and the closing tag, with a forward slash, signals its end.
• Proper nesting of tags is crucial for valid HTML structure and rendering; tags can be placed inside other tags to build layered content.
• Understanding the pairing and nesting of tags is essential for creating well-structured, accessible webpages.
