CSS, or Cascading Style Sheets, is the language used to style and enhance HTML documents. It defines the presentation of HTML elements on a web page, enabling changes to fonts, colors, sizes, spacing, column layouts, and animations.

What is CSS?

CSS, or Cascading Style Sheets, is a language used to style and enhance websites. It controls how HTML elements—such as text, images, and buttons—are displayed on a webpage. With CSS, you can adjust font sizes and colors, add backgrounds, and manage the layout, transforming a basic webpage into a visually appealing and user-friendly experience. CSS also simplifies layout management across multiple web pages by using external stylesheets stored in CSS files.

Different Ways to Use CSS

CSS has three ways to style the HTML:

Inline: Add styles directly to HTML elements using the style attribute (limited use).
Internal: Place styles within a <style> tag inside the HTML file, usually within the <head> section
External: Create a separate CSS file with a .css extension and link it to your HTML file using the <link> tag.
