Takeaways

• 😀 HTML is the foundation of the web and can be used to build systems beyond websites, including computer programs for Windows, Linux, and MacOS.
• 😀 HTML is essential for anyone learning web development, as it serves as the core language of the internet.
• 😀 The course is free but offers high-quality content comparable to paid courses, aimed at enhancing your professional skills.
• 😀 The file format for HTML is '.html', although '.htm' is also used, with '.html' being the more common and recommended choice.
• 😀 'Hypertext' refers to links that connect web pages, while 'markup language' indicates that HTML uses tags (labels) to structure content.
• 😀 Tags in HTML are enclosed in angle brackets (< >) and define elements like text, images, and videos, with the 'title' tag setting the page’s title.
• 😀 HTML has around 140 tags, though not all are commonly used, and some have become obsolete. It’s important to know which tags are essential.
• 😀 HTML tags can sometimes be intuitive (like <img>, <video>, <audio>) but others, like <ul> (unordered list) and <li> (list item), are based on English abbreviations.
• 😀 Understanding how tags work is crucial for web development, as it enables the creation of properly structured websites that browsers can interpret correctly.
• 😀 In the practical part of the lesson, the instructor demonstrates how to create a new HTML project and file using Visual Studio Code (VS Code) on Windows, emphasizing the importance of using proper file and folder naming conventions (e.g., no spaces).

Q & A

What is the importance of learning HTML?

Learning HTML is fundamental to understanding web development. It is the basic building block of the web and is used to structure content on the internet. HTML allows you to create websites, web applications, and even software for operating systems like Windows, Linux, and MacOS.

What does the acronym HTML stand for?

HTML stands for Hypertext Markup Language. It is a language used to create and structure content on the web, using markup tags to define the structure and meaning of different parts of a webpage.

What are the common file extensions for HTML files?

The most common file extension for HTML files is '.html'. You might also encounter '.htm' (without the 'L' at the end), but '.html' is the widely accepted standard.

What is a 'hyperlink' in HTML?

A 'hyperlink' or 'hypertext' refers to links that connect different documents or webpages. It allows users to click and navigate from one page to another. In HTML, links are created using the <a> tag.

What does the term 'markup language' mean in the context of HTML?

A markup language like HTML uses tags (or 'markup') to define the structure of a webpage. Tags are written using angle brackets (<>) and are used to specify elements like headings, paragraphs, links, and other content on the page.

What is the role of the <title> tag in HTML?

The <title> tag is used to define the title of a webpage. This title appears in the browser tab or window when the page is open, helping users identify and navigate between multiple open tabs.

Can you name some of the most commonly used HTML tags?

Some commonly used HTML tags include <img> for images, <video> for videos, <audio> for audio files, <ul> for unordered lists, and <li> for list items. These tags help structure content in a way that is understandable by browsers.

What is the significance of naming folders without spaces in web development?

It is recommended to avoid using spaces in folder names for web development projects to prevent issues later when linking to files. Using hyphens (-) or underscores (_) is preferred for clarity and ease of use, especially when working with URLs.

How do you create an HTML project in Visual Studio Code?

To create an HTML project in Visual Studio Code, first create a folder where you want your project to reside. Then, open Visual Studio Code, select 'File' -> 'Open Folder' and navigate to the folder you just created. You can then add your HTML files, such as 'index.html', to begin building your website.

Why is 'index.html' the default name for a webpage?

'index.html' is the standard name for the homepage of a website. When you visit a website, the server looks for the 'index.html' file by default and loads it as the homepage of the site.
