What is CSS?
CSS, or Cascading Style Sheets, is a stylesheet language used to describe the presentation of a document written in HTML or XML. CSS allows you to control the color, font, layout, and overall visual style of a webpage.
Why Use CSS?
CSS is essential for web design. It helps you separate the content from the design, making it easier to manage and update styles across a website. With CSS, you can create visually appealing web pages, improve user experience, and ensure consistency.
How Does CSS Work?
CSS works by selecting HTML elements and applying styles to them. A CSS rule consists of a selector and a declaration block. The selector points to the HTML element you want to style, and the declaration block contains one or more declarations that define the style.

style
attribute within HTML tags. - Internal CSS: Written within a
<style>
tag in the HTML document's<head>
. - External CSS: Placed in an external file with a
.css
extension, allowing you to apply styles across multiple pages.
