What is CSS file?

A CSS file is considered a cascading style sheet (CSS) file for formatting web page content. This file has configurable global properties on the display of HTML elements. For example, CSS files determine the size, color, font, line spacing, indentation, borders, and where HTML elements should be placed.

Additional data

CSS was introduced in 1996 by the W3C. Web developers and designers use CSS files to create consistent looks and feel for every page on the site. CSS files store the display properties of several pages in a single file and reduce the amount of work with the amount of generated HTML code.

Any web page that links to a CSS file will change based on the properties of the CSS file. For example, the designer can change the font and add padding to the text. When a page links to the same CSS file, it will only need to change a single CSS file, not all individual pages.
