Overview
csslib is a Dart library designed for parsing and analyzing CSS (Cascading Style Sheets). It enables developers to read, interpret, and manipulate CSS syntax programmatically. The library supports standard CSS features and is useful in environments where CSS needs to be processed dynamically, such as in build tools or style validators. It is part of the Dart Tools suite and is compatible across all major platforms including web, mobile, and desktop. This makes it ideal for integrating CSS analysis into Flutter or Dart-based applications that require stylesheet processing.
