What is an SCSS file?
Style sheet that contains Sass language; similar to a .CSS file but with added capabilities, such as variables, nested rules, and mixins; used to format contents of a Web page.
SCSS files are stored in a plain text format. The SCSS language does not technically replace or extend CSS. The files are compiled into CSS files, using programs such as CodeKit and Compass.app, and are then used for formatting Web page contents.
