Beginner’s Guide to CSS

Published on August 15, 2025

CSS, or Cascading Style Sheets, is the language that controls how your HTML content looks. If HTML is the structure of your website, CSS is the paint, the layout, and the design that makes it beautiful.

Why Learn CSS?

CSS allows you to change colors, fonts, spacing, and even create animations. Without it, websites would be plain and boring.

Basic CSS Syntax

CSS works by selecting HTML elements and applying styles to them:

selector {
    property: value;
}

Example

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

This code makes all paragraphs red with a font size of 16 pixels.

Ways to Add CSS

  • Inline CSS: Inside the HTML element using the style attribute.
  • Internal CSS: Inside a <style> tag in the HTML head.
  • External CSS: In a separate .css file linked to the HTML.

Next Steps

Once you know the basics, you can explore topics like Flexbox, Grid, and responsive design to make your sites look great on any device.
