csstidy 1.4-5 (arm64 binary) in ubuntu zesty

 csstidy parses and optimises your CSS code, making it cleaner and more
 concise. The end result is a smaller CSS file and better written code. It
 has a variety of option settings giving the user a significant amount of
 control over the level of file compression and readability. It is not meant
 to be a CSS validator.
