A website page layout extractor should map a captured page from top to bottom, identify the role of each section, and explain how spacing, surfaces, typography, and components work together. The useful outcome is a layout blueprint you can hand to a designer or developer, not a vague description of the page.

If you are starting with a URL, add the page through the Fudge browser extension first. The capture gives you a concrete page state to inspect, including its visible structure and styling. Treat the result as an observed guide for that capture, not as proof of every rule used across the wider site.

Start with the page structure

Capture the page in layers:

1. Page flow: List the header, hero, supporting sections, feature groups, proof, calls to action, footer, and any repeated modules in order.
2. Section purpose: Give each section a one-line job, such as introduce the product, explain a workflow, compare options, or answer objections.
3. Layout shape: Record full-width bands, centered containers, split columns, card grids, sidebars, overlapping elements, and intentional empty space.
4. Responsive changes: Note which columns stack, which controls collapse, how headings wrap, and which elements change order or disappear.
5. Visual hierarchy: Explain what draws attention first, second, and third through size, contrast, position, and spacing.

The first decision is whether you need a layout map or a design-system extraction. A layout map describes the page's structure and relationships. A design-system extraction adds typography, colors, spacing, borders, radii, shadows, gradients, and component rules. For a redesign, request both, but keep the page-specific structure separate from the reusable rules.

Open the examples below and compare the two Linear captures as a pair. Both use Inter, a near-black canvas, muted dividers, compact controls, and a cool accent. The second capture shows the same typography, spacing, surfaces, and interaction treatment on another page. That makes the pair useful for separating repeated system choices from one-off page content.

Build a layout blueprint

For every section, record:

• Section name and purpose
• Container width and alignment
• Number of columns and their approximate proportions
• Gap sizes and vertical spacing rhythm
• Surface treatment and boundaries
• Heading, body, label, and button hierarchy
• Media placement and crop behavior
• Repeated components and their states
• Narrow-screen changes

Use plain language. "Two-column feature section with copy on the left and a product panel on the right" is more actionable than "asymmetric composition." If exact measurements are available, include them. If they are not, label the result as an estimate and preserve the relationship: the headline is larger than the body, the card gap is smaller than the section gap, and the content aligns to the same container edge.

Separate reusable rules from page content

A strong extraction has two parts. The page blueprint describes this specific URL: section order, copy blocks, media, and component placement. The shared style guide describes choices that appear across the site: font families and weights, text sizes, line heights, surface colors, divider treatment, corner radii, shadows, and spacing steps.

The Linear typography example is a good model for this distinction. Inter at weight 400 is used for body copy, labels, navigation, and controls, while weight 500 supports headings and emphasized interface text. That tells you how emphasis works without pretending that every page has identical content.

Do not treat an extracted layout as the site's official internal design system. It is an observed guide based on the captured page or pages. Verify tokens against source files, inspect additional states, and ask the owning team before turning the result into shared production components.

Before implementation, run a short review. Confirm that the page order is correct, the primary action is visible at the intended viewport, repeated components are grouped consistently, and mobile behavior is described rather than assumed. Compare at least one secondary page if you want to identify site-wide rules.

Then turn the blueprint into a build checklist: canvas and container setup, type scale, spacing scale, section templates, component states, responsive breakpoints, and visual QA points. If you want code-ready output, ask for the observed details in Tailwind v4, CSS, JSON, or DESIGN.md form after the visual review. The format should follow the work you need to do next, not replace the inspection.

Use this in your AI agent

> Inspect the captured website page from top to bottom and create a layout blueprint. List the page sections in order, explain each section's purpose, map containers, columns, gaps, surfaces, typography hierarchy, components, media placement, and responsive changes. Compare the supplied reference captures to separate reusable site-wide style rules from page-specific content, then finish with a verification checklist for rebuilding the page.

Compare at least two pages and look for repetition in relationships rather than repeated words. A reusable choice usually appears in several places: the same container edge, heading scale, card radius, divider style, button treatment, surface color, or vertical spacing rhythm. A page-specific choice usually depends on one section's content, such as a special hero split, a one-off illustration, or a custom comparison table.

The two supplied Linear captures help with this comparison. They share Inter, near-black surfaces, muted dividers, compact controls, and a cool accent. Those are reasonable candidates for shared rules because they appear across both captures. The exact section order or product message should remain page-specific.

Create two columns in your notes: "repeated pattern" and "local exception." For each repeated pattern, add where it appears and how confident you are. Before coding it as a shared component, check another page or state. This avoids turning a single clever layout into a rule that makes later pages harder to build.

Ask for a structured handoff with five parts. First, include the section order and each section's purpose. Second, describe the container, columns, alignment, spacing, surfaces, and component placement. Third, document typography roles with family, weight, size, line height, and casing when those details are observable. Fourth, explain responsive changes at narrow widths. Fifth, list implementation checks that a developer can verify in a browser.

Request estimates to be labeled as estimates. Preserve relationships when measurements are uncertain, such as a larger section gap than card gap or a heading aligned to the same container as the button. Ask for repeated components to be described once and referenced consistently.

A useful final format is: page blueprint, reusable style rules, component inventory, responsive behavior, open questions, and QA checklist. If code is needed, request it only after the blueprint is reviewed. That keeps implementation output tied to what the page actually shows.
