CSS Basics

CSS (Cascading Style Sheets) is a style sheet language that describes the presentation of web pages. Whereas HTML is what forms the structure of a web page, CSS is what we use to style the HTML with colors, backgrounds, font sizes, layout, and more. As you'll soon learn, CSS is one of the core technologies for designing and building websites.

Understanding Values and Units 

Every CSS property has a set of values it can accept. Most properties accept keywords that literally describe a value. Many properties also accept numbers, functions, length values, or a URL. In this stage, you'll learn the common values and units CSS properties accept.

The Box Model 

The box model is the basis of CSS layout because it dictates how elements are displayed and how they interact with each other.

Basic Layout
