Opening CSS files

Did your computer fail to open a CSS file? We explain what CSS files are and recommend software that we know can open or convert your CSS files.

What is a CSS 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 that have been written in the HTML and XHTML programming languages, the format can also be applied to any type of XML document.

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 HTML elements.

CSS files are similar to template files, allowing users to create multiple websites featuring a similar look and feel without having to create each and every site from the ground up.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
