Introduction to HTML and Webpage Structure

Introduction:

Welcome to the first lesson of the “HTML for Web3 Frontend Development” section in our AI-enhanced Web3 Frontend Development Course.

This lesson is tailored for those embarking on their journey into the world of web development, especially in the context of Web3 technologies. It is designed for beginners, regardless of whether you have prior coding experience.

Remember, watching the lesson video will offer a deeper understanding of this topic.

Learning Objectives:

By the end of this lesson, you will be able to:

1. Grasp the fundamental concept of HTML and its role in web development.
2. Understand the basic structure of a webpage.
3. Recognize how HTML forms the backbone of web pages, especially in the Web3 context.

What is HTML?

HTML, or HyperText Markup Language, is the foundational language used to create and structure content on the web.

It is not a programming language; rather, it’s a markup language that defines the structure and layout of a web page by using various tags and attributes.

In the realm of Web3, HTML remains a cornerstone. It provides the structure for decentralized applications (dApps) and other blockchain-based platforms, ensuring that users have a coherent and navigable interface.

Webpage Structure in HTML:

A typical HTML webpage structure includes several key components:

• DOCTYPE Declaration: It tells the web browser about the version of HTML used in the document.
• HTML Tag: This is the root element that encloses all your HTML code.
• Head Section: Contains meta-information about the webpage, like its title and links to scripts and stylesheets.
• Body Section: This is where the actual content that’s visible to users goes, such as text, images, links, and more.

NOTE: HTML file is saved using .html file extension

HTML Comment:

An HTML comment is a useful feature that allows developers to include explanatory notes in the code, which do not display in the web browser or affect the layout and behavior of the webpage. Comments are primarily used to describe parts of the HTML code to enhance readability and maintainability, making it easier for developers to understand the codebase, especially in collaborative environments.

To create a comment in HTML, you wrap the text you want to be commented out within <!-- and --> tags. Here is the syntax for adding a comment in HTML:

<!-- This is a comment in HTML -->

Comments can be single or multi-line and are often used to:

• Explain the purpose or logic behind sections of HTML.
• Temporarily disable code that should not be deleted but isn’t currently needed.
• Provide instructions or warnings to other developers working on the same codebase.
• Include TODO notes for future reference and action items.

It’s important to note that while comments are invisible to the end-user and do not render in the browser, they are still part of the source code and can be viewed by anyone who inspects the webpage’s source.

Here is an example of a multi-line comment in HTML:

<!--
  This is a multi-line comment.
  Use comments to explain the HTML code and make it more readable.
  You can include as many lines as you wish.
-->

When writing HTML for Web3 applications, comments can be particularly useful for distinguishing between different parts of the code that interact with blockchain functionality, such as smart contract calls or cryptocurrency transactions. They help keep the code organized and understandable, especially as the complexity of the application increases.

HTML in Web3 Development:

In Web3, HTML structures the frontend of dApps and blockchain interfaces. Understanding HTML is crucial for creating user-friendly, accessible, and aesthetically pleasing decentralized applications.

Conclusion:

HTML is the starting point of your journey into web development.

It’s the skeletal framework upon which all websites and web applications, including those in the Web3 space, are built.

Mastery of HTML is essential for any aspiring Web3 developer.

Support:

If you need help with this lesson, questions, suggestions and improvement. The best way to get help is to use the comment below:
1. First check existing comments if your questions have been answered before posting.
2. If no existing related question with an answer, then you can post a new one (kindly avoid duplicating previously asked and answered questions).

NOTE: This is the most recommended way of getting support directly from the instructor of this course. Posting on other platforms like Discord may get support from other community members and not from the course instructor directly.

Images|Videos|Links: To support your question with a screenshot, Github repo link or other media, kindly upload it somewhere online like Drive/Dropbox or Github (for codes) first, then post the link to it in your comment. Please do not upload media/codes directly, it may fail or cause your comment to be deleted.

Please ONLY post questions that are specific to this lesson not the entire course to ensure others can find it helpful. Each lesson allows comments relating to it ONLY. Off-lesson questions will be deleted even if they relate to this course as a whole but as long as they are not specific to this lesson, they are not allowed.
