Since loading these files takes time and extra requests from the browser, we try to reduce their number and size. The tricky part is to identify which scripts are required on which pages. Sometimes we can figure this out automatically, but considering all the cases with various themes, widgets and other plugins that add their own modifications it is unavoidable that you optimize your site manually.

.min.css. By default, debugging mode is off.
