Introduction

HTML and CSS are the backbone of the web, allowing developers to structure content and define its look and layout.

Understanding HTML

Basic Structure: An HTML document is structured with the <!DOCTYPE html>, <html>, <head>, and <body> tags.
Common Tags: Learn about <h1> to <h6> for headings, <p> for paragraphs, <a> for links, <img> for images, and <div> for divisions or sections of the page.

Styling with CSS

Selectors, Properties, and Values: CSS uses selectors to target HTML elements, properties to choose what aspect of the element to style, and values to define the appearance.

Example:

p {
    color: blue;
    font-size: 16px;
}

Responsive Design: Utilize media queries to make designs that adapt to different screen sizes.

@media (max-width: 600px) {
    .container {
        width: 100%;
    }
}
