What is CSS? CSS is a style sheet language used to control the appearance of a web page. It allows you to style HTML elements and make them visually appealing. If HTML is the skeleton of a web page, then CSS is the clothing and design that makes it look good and user-friendly.

CSS allows you to define things like:

• Colors (background colors, text colors)
• Font styles (type, size, spacing)
• Layout (positioning elements, margins, padding, etc.)
• Visual effects (borders, shadows, transitions)

What CSS does:

• Controls the layout and position of elements on a web page (e.g., centering text, creating columns).
• Enhances design by adding colors, fonts, borders, and other visual styles.
• Makes websites responsive, adjusting their layout for mobile or desktop views.

Example of CSS:

body {
font-family: Arial, sans-serif;
background-color: #f4f4f4;
}

h1 {
color: #333;
text-align: center;
}

p {
color: #555;
line-height: 1.6;
}
