1. Introduction to HTML & CSS

Welcome to the world of web development! Here, HTML (HyperText Markup Language) and CSS (Cascading Style Sheets) form the foundational building blocks. Why, you ask? Well, HTML structures the content, while CSS designs and styles it.

Think of HTML as the skeleton of a web page. It comprises of tags that enclose different parts of content. The common tags include <h1> to <h6> for headers, <p> for paragraphs, and <a> for links.

<p>This is a paragraph.</p>

Above is a simple HTML code snippet demonstrating a paragraph element.

Moving on to CSS, it’s the creative layer adding colors, fonts, and layouts to our web page. CSS can be inline, internal, or external. However, for maintainability, we prefer the external CSS.

body {
background-color: lightblue;

This is a basic CSS rule setting the body’s background color to light blue.
