overview

What weasyprint does

WeasyPrint loads one connected HTML document, applies its embedded styles and an optional --stylesheet file, then writes a PDF artifact. CSS print rules control page size, margins, breaks, headers, and other paged-media behavior.

Enable --presentational-hints when legacy HTML attributes such as width, align, or bgcolor should influence rendering. Modern documents should express those choices in CSS instead.

This is an HTML/CSS renderer, not a browser automation node. It does not execute application interactions or wait for client-side JavaScript to populate a page.
