CSS Introduction

What is CSS?

CSS stands for Cascading Style Sheets. CSS describes how HTML elements are to be displayed on screen. CSS saves a lot of work — it can control the layout of multiple web pages all at once.

Why Use CSS?

  • Separates content from design
  • One stylesheet controls many pages
  • Makes pages load faster
  • Easy to maintain and update
