Package css is a pure-Go, hand-written CSS engine: it tokenizes and parses CSS (CSS Syntax Level 3), matches selectors against a DOM with correct specificity, and runs the cascade and inheritance to compute the effective style of each element.

Package epub is a read-only EPUB reader: it opens the container, walks META-INF/container.xml to the OPF package document, and extracts the spine documents' body markup in reading order plus their stylesheets — the pieces the HTML pipeline lays out (EPUB content IS XHTML, so the reflow engine does the real work).
