Minification or compression means removing all unnecessary characters, such as spaces, new lines, comments, without changing the functionality of the source code. During development and debugging, these characters make code easier to read. At the production stage, they only increase the size of code to be transferred.
To minify your code automatically, you need to configure a CSSO File Watcher which will track changes to your files and run CSSO.
The generated minified code is stored in a separate file with the name of the source CSS file and the extension min.css. The location of this generated file is defined in the Output paths to refresh field of the New Watcher dialog. However, in the Project Tree, the file with the minified code is shown under the source CSS file which is displayed as a node. To change this default presentation, configure file nesting in the Project tool window.
