CSS stands for Cascading Style Sheets. It is a style sheet language used for describing the presentation of a document written in a markup language such as HTML or XMLAd1. CSS allows you to control how elements should be rendered on screen, on paper, in speech, or on other media2. CSS is one of the core technologies of the web, along with HTML and JavaScriptAd1.
CSS works by using rules that specify the styles that apply to particular elements or groups of elements on a web page. Each rule consists of a selector that matches the elements, and a declaration block that contains one or more declarations that set the style properties and values.
