About 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.	About Modern security teams are “paving the road” for developers — enforcing code guardrails on every commit. r2c’s Semgrep can eliminate vulnerability classes organization-wide. Scale your security team with lightweight static analysis. Semgrep is a fast, open-source, static analysis tool that excels at expressing code standards — without complicated queries — and surfacing bugs early in the development flow. Precise rules look like the code you’re searching; no more traversing abstract syntax trees or wrestling with regexes. Start right away with 900+ rules and SaaS infrastructure to get fast results in your editor, at commit-time, or in CI. When off-the-shelf rules aren’t enough, quickly and intuitively write custom rules to express your unique code standards. Rules look like the code you’re searching. For example, rules for Go look like Go. Find function calls, class or method definitions, and more without having to understand abstract syntax trees or wrestle with regexes.
