What Webflow's published code actually contains

A published Webflow site is real, static HTML and CSS — bloated, but honest. Understanding what's in it tells you exactly what's safe to keep and what's safe to strip.

Every site ships three stylesheets (normalize.css, the shared webflow.css framework, and your project CSS), jQuery 3.5.1, and webflow.js. The interaction engine (IX2) stores its animations as JSON in an inline script and binds them to elements via data-w-id attributes.

Responsiveness is pure CSS: a ~992px desktop base with max-width overrides at 991/767/479 and min-width steps above. That means tablet and mobile are the same DOM under different media queries — which is why a faithful mirror that keeps the real CSS reproduces every breakpoint exactly.

The load-bearing parts are the stylesheets, jQuery+webflow.js (for any component or interaction), and the IX2 JSON. Strip those and the page may look right but stop working. FrameFlow keeps them, localizes every asset, and verifies the result.
