Lesson 1: What is HTML?
Overview:
In this lesson, we'll explore the fundamental concepts of HTML (Hypertext Markup Language) and its role in web development. HTML forms the backbone of every webpage, providing the structure and content that users interact with. Understanding HTML is the first step towards becoming proficient in web development.
Key Concepts:
1. Definition of HTML:
- HTML stands for Hypertext Markup Language.
- It is the standard markup language for creating web pages.
- HTML defines the structure and layout of a web document by using a variety of tags and attributes.
2. Purpose of HTML:
- HTML is used to structure content on the web.
- It provides a way to organize text, images, links, and other media into a coherent presentation.
- Web browsers interpret HTML to render web pages visually for users.
3. Key Components of HTML:
- Tags: HTML documents are made up of HTML tags, which are enclosed in angle brackets (< >).
- Elements: Tags, along with their content, form HTML elements. For example, `<p>` is a paragraph element.
- Attributes: Tags can have attributes that provide additional information about the element. Attributes are added to the opening tag.
Examples and Demonstrations:
- Example of a simple HTML document structure.
- Explanation of basic HTML tags such as `<html>`, `<head>`, `<title>`, `<body>`.
- Demonstration of how web browsers interpret HTML to display content.
Activities:
1. Hands-on Exercise:
- Create a simple HTML document using a text editor.
- Include basic HTML tags to structure the document (e.g., headings, paragraphs).
- View the document in a web browser to see how HTML is rendered.
2. Discussion:
- Discuss real-world examples of HTML usage on popular websites.
- Explore the source code of a webpage to identify HTML elements and their purpose.
Summary:
In Lesson 1, we've learned the foundational concepts of HTML, including its definition, purpose, and key components. Understanding these concepts is essential for anyone interested in web development, as HTML forms the basis of all web content. In the next lessons, we'll dive deeper into HTML syntax, tags, and advanced features.
