CSS Introduction

CSS is the language we use to style a Web page.

What is CSS?

  • CSS stands for Cascading Style Sheets
  • It describes how HTML elements are to be displayed on screen, paper, or in other media
  • CSS saves a lot of work — it can control the layout of multiple web pages all at once
  • External stylesheets are stored in .css files

Why Use CSS?

CSS is used to define styles for your web pages, including the design, layout, and variations in display for different devices and screen sizes.

CSS Example

body {
  background-color: lightblue;
}
 
h1 {
  color: white;
  text-align: center;
}
 
p {
  font-family: verdana;
  font-size: 20px;
}

CSS Solved a Big Problem

HTML was never intended to contain tags for formatting a web page!

HTML was created to describe the content of a web page, like:

<h1>This is a heading</h1>
 
<p>This is a paragraph.</p>
