Cascading Style Sheets (CSS) is a style sheet language used for describing the presentation of a document written in a markup language such as HTML. SVG also supports the use of CSS.
Unlike CSS 2, which is a large single specification defining various features, CSS 3 is divided into several separate documents called "modules". Each module adds new capabilities or extends features defined in CSS 2, preserving backward compatibility.
css3-box : CSS3 basic box model
css3-multicol : https://www.w3.org/TR/css-multicol-1/
css3-page : http://www.w3.org/TR/css3-page/
One of flexbox's advantages is the ability to easily align items within the container to the center of a page, both vertically and horizontally.
