Blitz is an HTML and CSS rendering engine and native UI framework designed to translate web-standard markup into visual interfaces for native applications. It functions as a layout engine that converts raw HTML strings into a structured object model for programmatic rendering.
The project implements a web-standard layout engine using Flexbox and Grid models to compute element positions and sizes. It includes a dedicated SVG graphics renderer for displaying scalable vector graphics embedded within HTML-based layouts.
The framework covers native windowing integration and system accessibility to enable cross-platform UI development. Its capability surface includes CSS-driven style resolution, pointer interaction handling, and the ability to animate interface elements and apply visual effects. It also manages resource loading via HTTP and local filesystems to populate rendered documents.
