CSS (Level 2)

The first part of the pre-course will provide you with an overview of CSS and resources to cover the basics that you need.

Introduction to CSS

CSS is the language we use to style a Web page.HTML was NEVER intended to contain tags for formatting a web page! HTML was only created to describe the content of a web page, like:

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

When tags like <font>, and color attributes were added to the HTML 3.2 specification, it started a nightmare for web developers. The development of large websites, where fonts and color information were added to every single page, became a long and expensive process. To solve this problem, CSS was created. CSS removed the style formatting from the HTML page!

What is CSS?

• CSS stands for Cascading Style Sheets

• CSS describes how HTML elements are to be displayed on the 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
