What is a CSS file?

Cascading Style Sheet File
CSS is an acronym for Cascading Style Sheet. Files that contain the .css file extension are used to format the contents of an associated web page. While the CSS file format is most commonly associated with website pages written in the HTML and XHTML markup languages, it can also be applied to XML documents.
A CSS file contains the properties that define how the HTML elements of an associated web page will be displayed, such as the color, font, size, line spacing, borders, and other visual elements.
CSS files are similar to template files, allowing users to create multiple websites featuring a similar look and feel without making every site from the ground up.
