HTML Webpage Design Part 2: Basic structure of a webpage

HTML Tag Fundamentals
📌 An HTML tag is a rule enclosed in pointy brackets (``) that applies a specific behavior to the content that follows it.
➡️ Tags require an opening tag and a closing tag (which includes a forward slash, e.g., ``) to define where the rule starts and stops being applied.
🖥️ Web browsers interpret these tags; the actual tag code is not directly visible on the rendered webpage, only the applied rule is seen.

Basic HTML Document Structure
🔗 The fundamental structure of an HTML document must start with an opening `` tag and end with a closing `` tag, enclosing all other content.
🧠 The structure is compared to a human body: it consists of two main sections: the `` and the ``.
📝 The `` section contains metadata or information *about* the web page (like the brain), which is generally not visible on the page itself.
👁️ The `` section contains all the visible content that users actually see in the browser window.

Implementing the Title Tag
🔖 The ``.
🔄 When making changes to the HTML file (e.g., adding a title like "Mr. Long Education - Home"), you must save the file and then refresh the browser to see the update.

Key Points & Insights
➡️ Use text editors like Notepad++ as they offer helpful features, such as highlighting matching open/close tags (turning them purple) to easily debug structural errors.
➡️ Indentation is recommended when writing HTML to visually organize nested tags within the `` and `` structures for better readability.
➡️ The visible page content is entirely determined by what is placed inside the `` tags, while the `` controls background information like the page title.
