Cascading Style Sheet (CSS) is a style sheet language used to style documents written in a markup language like HTML and XML. It allows developers to control how the webpage should be displayed by applying styles ( e.g color, font, space). Before CSS, all the styles and formatting were explicitly defined within HTML. Due to this, the creation of large websites became a long and expensive process. This is because, for every single page, style information has to be added repeatedly. For the solution of this problem, the World Wide Consortium (W3C) introduced CSS in 1996. CSS file is an independent file and is saved with [dot] CSS (.css) extension. Now developers can write the style information of the web pages to a separate style sheet. The separation of HTML and CSS i.e content and styling, makes it easier to maintain sites, improves content accessibility, share style sheets across pages and provides more flexibility. CSS3 is the latest version of the Cascading Style Sheets language and extends CSS2.1.

Introduction

Cascading Style Sheet (CSS) is a style sheet language used to style documents written in a markup language like HTML and XML. It allows developers to control how the webpage should be displayed by applying styles ( e.g color, font, space). Before CSS, all the styles and formatting were explicitly defined within HTML. Due to this, the creation of large websites became a long and expensive process. This is because, for every single page, style information has to be added repeatedly. For the solution of this problem, the World Wide Consortium (W3C) introduced CSS in 1996. CSS file is an independent file and is saved with [dot] CSS (.css) extension.

Now developers can write the style information of the web pages to a separate style sheet. The separation of HTML and CSS i.e content and styling, makes it easier to maintain sites, improves content accessibility, share style sheets across pages and provides more flexibility. CSS3 is the latest version of the Cascading Style Sheets language and extends CSS2.1. It has several new features like shadows, gradients, rounded corners transitions or animations, and new layouts like a multi-columns, flexible box or grid layouts. The CSS specifications are maintained by the World Wide Consortium (W3C). The latest snapshot of CSS published by it is available at https://www.w3.org/TR/css-2018
