What Is A Css File? It Is Used For What Purpose?

CSS stands for “Cascading Style Sheets”, and are used to control and manage font styles, font sizes, and web site color combinations that are used in a web page. In order to retain continuity of “look and feel” throughout a website, all pages within a website will often refer to a single CSS file.
The CSS file is typically contained in a separate file from the website, and the various web pages retrieve the CSS file each time a web page is displayed. CSS files make global appearance changes easy — a single change in a CSS file will mean that any pages using that CSS file will automatically display the changes.
