A 'DOCTYPE' declaration is necessary at the beginning of an HTML file to inform the browser about the version of HTML being used. It helps ensure that the browser renders the page correctly according to the specified standard.

How does the Live Server extension help in web development?

The Live Server extension helps in web development by automatically reloading the web page in the browser whenever changes are made to the code, allowing developers to see updates in real-time without manually refreshing the page.

What is the W3C Markup Validation Service and how is it used?

The W3C Markup Validation Service is a tool provided by the World Wide Web Consortium that checks HTML documents for errors and warnings. It helps developers ensure that their web pages adhere to web standards and are free from common mistakes.

What are some recommended extensions for Visual Studio Code to enhance web development experience?

Some recommended extensions for Visual Studio Code to enhance web development include 'Dark New Tab' for a dark-themed new tab page, 'vscode-icons' for file and folder icons, 'GitHub Theme' for a dark or light theme based on GitHub's style, and 'Live Server' for live previewing of web pages.
