The stylesheet in an export should be something you can open and understand. That matters because PortfolioDIY is not just showing you a hosted page; it is giving you files you may want to maintain later.

PortfolioDIY generates CSS for the site you built. The exporter walks the site structure, sections, components, and token values, then writes the rules that export needs.

The output is organised the way a careful human would organise it: design tokens as custom properties first, then base element styles, then one BEM block per section in page order. Class names read like the page (.hero__title, .projects__card), so finding the rule you want takes seconds, not a search.

The goal is not a clever size claim. The goal is a stylesheet that starts with tokens, follows the page structure, and stays readable after it leaves the editor.
