PostCSS is a versatile tool that transforms CSS using JavaScript plugins, enabling a wide range of functionalities such as linting, supporting variables and mixins, transpiling future CSS syntax, and inlining images. It serves as a framework for developing CSS tools and can be utilized to create template languages similar to Sass and LESS. The core of PostCSS comprises a CSS parser that generates an abstract syntax tree, a set of classes that form the tree, a CSS generator that produces a CSS line for the object tree, and a code map generator for CSS changes. Plugins operate on the object tree, analyzing and modifying it before PostCSS generates a new CSS string reflecting these changes. Notable plugins include Autoprefixer, which adds vendor prefixes, and Stylelint, a modern CSS linter that enforces consistent conventions and avoids errors in stylesheets. PostCSS is employed by industry leaders such as Wikipedia, Twitter, Alibaba, and JetBrains.

TrifleJS is a headless browser designed for test automation, utilizing the .NET WebBrowser class and the V8 JavaScript engine to emulate Internet Explorer environments. Its API is modeled after PhantomJS, making it familiar to users of that framework. TrifleJS supports various versions of Internet Explorer, allowing emulation of IE7, IE8, and IE9, depending on the installed version. Developers can execute scripts via the command line, specifying the desired IE version for emulation. The platform offers an interactive mode (REPL) for debugging and testing JavaScript code.
