Learning CSS – An Introduction

CSS (Cascading Style Sheets) is the language used to style elements on a web page. It separates the content (HTML) from the presentation, making websites more efficient and maintainable.

Understanding the Basics

• Selectors: These are used to target specific HTML elements to which you want to apply styles.
  • Example: body, h1, .class-name, #id-name
• Properties: These define the styles you want to apply.
  • Example: color, font-size, background-color, margin, padding
• Values: These specify the value for a property.
  • Example: red, 16px, #f0f0f0, 10px, 20px

Basic CSS Structure:

CSS

selector {
  property: value;
}

Use code with caution.

Example:

CSS

h1 {
  color: blue;
  font-size: 36px;
}

Use code with caution.
