Many sites use custom web fonts, so standard OS fonts are considerably less common than they were! Avoid import The import at-rule allows any CSS file to be included within another. Concatenate and Minify Most build tools allow you to combine all partials into one large CSS file that has unnecessary whitespace, comments and characters removed.

In some cases, separate files may be beneficial if you have smaller, regularly-changing CSS assets. However, most sites are likely to benefit from sending a single file that is immediately cached by the browser. Minification may not bring considerable benefits when you have GZIP enabled. Finally, you could consider a build process that orders properties consistently within declarations.
