PostCSS HTML Syntax is a PostCSS plugin that enables parsing and processing of HTML (and HTML-like) files, including Vue Single-File Components, Svelte Components, Astro Components, and more. It allows developers to lint and process CSS within `<style>` tags and inline styles in HTML files using tools like Stylelint. This tool is particularly useful for frontend developers working with modern frameworks and tools that embed CSS in HTML-like structures.
