About FB2

FictionBook XML-based ebook.

FB2 (FictionBook) is a single XML file containing an entire book — title-info, sections, poetry, citations, and base64-encoded images all in one. This viewer parses it natively with DOMParser, transforms FB2 markup (sections, epigraphs, poems, stanzas) into clean HTML, decodes embedded binaries into blob URLs, and renders the book with Fraunces display type, indented paragraphs, and an electric-green chapter rail. Handles both UTF-8 and legacy windows-1251 encodings.
