A website component styles extractor from a URL should show how repeated parts of a site are built, not only list their colors. The useful result compares buttons, cards, inputs, navigation, tabs, badges, and content sections across pages so you can reuse the patterns with fewer guesses. [Fudge's website design system extraction feature](/features/extract-design-system-from-website) supports this kind of visual comparison.

## Make the component shortlist first

Begin with the components that shape the visitor's experience:

1. **Navigation:** Check logo treatment, links, active states, spacing, dividers, menus, and mobile behavior.
2. **Buttons:** Record height, padding, radius, border, fill, text weight, icon spacing, and visible hover or disabled states.
3. **Inputs:** Compare labels, placeholder text, borders, focus treatment, errors, helper text, and selected values.
4. **Cards:** Note surface color, padding, border, shadow, image ratio, title spacing, metadata, and actions.
5. **Content blocks:** Look at hero sections, pricing rows, feature sections, testimonials, tables, tabs, and repeated lists.

For each component, record the shared rule first and the exceptions second. A button may use one radius and padding across the site while changing only its color by context. A card may keep its surface and spacing while switching from a border to a shadow on a featured section.

Open the examples below and compare the first screen before borrowing a pattern. The two captured Linear pages show a consistent near-black canvas, muted dividers, compact controls, and one cool accent. Their shared treatment is a useful example of how to describe component styling in context. The typography reference also identifies Inter at regular weight for body copy, labels, navigation, and controls, with a 500-weight variant for headings and emphasized interface text.

## Linear typography

- **Inter** — weight 400 · Body copy, labels, navigation, and controls.
- **Inter** — weight 500 · Headings and emphasized interface text.

## Compare the same component across pages

Do not extract one button or card in isolation. Find the same component in at least two places and compare size, spacing, text and icon alignment, background, border, text color, corner radius, shadow, visible states, and relationship to nearby content.

This prevents a promotional button from being mistaken for the default button. It also reveals whether a card style is shared or belongs only to a particular section.

Create a simple component record for every repeated pattern:

```text
Component: Button
Variants: primary, secondary, text
Size: observed height and horizontal padding
Typography: family, weight, size, line height
Surface: fill, border, text color
Shape: radius and border width
States: visible hover, focus, disabled, or selected treatment
Locations: pages and sections where it appears
Open questions: states or breakpoints not visible
```

Keep the wording factual. Say that a border appears muted on the captured page, not that it is the official border token. Say that a button appears compact, then record measured dimensions when they are available.

## Check the surrounding layout

A component's style depends on its surroundings. A card with 24 pixels of internal padding can feel spacious in a wide desktop grid and crowded in a narrow sidebar. A button may look balanced because of its line height and icon alignment, not because of padding alone.

Inspect the component's container width, neighboring gaps, alignment, and section background. For responsive work, compare the same component at more than one viewport. Look for changes in stacking, text wrapping, control width, image crop, and navigation behavior.

Typography deserves special attention. Confirm whether headings use the same family as body text, whether weight creates hierarchy, and whether labels use all caps, tighter tracking, or a smaller size. The captured Linear typography example shows how a compact sans-serif system can create contrast through size, weight, and muted color without needing many font families.

## Turn observations into reusable styles

After the comparison, define shared tokens before writing component rules. Name roles such as `surface`, `surface-muted`, `text`, `text-muted`, `border`, `accent`, and `radius-control`. Then map each component to those roles.

Build one default variant and one important alternate first. Test both in the page layout where they were observed. If the result feels wrong, check container spacing, type weight, and contrast before changing the component itself. Small local fixes should not hide a larger layout mismatch.

Export the handoff in CSS, Tailwind v4, JSON, or DESIGN.md when another person needs to implement it. Include page references, visible states, and an open-questions list. This extracts observed component styling while avoiding the claim that you recovered the website's private internal rules.

## Use this in your AI agent

> Inspect the website at [paste URL] and extract its repeated component styles. Compare navigation, buttons, inputs, cards, tabs, badges, hero sections, lists, and other recurring blocks across available pages and viewports. For each component, report variants, dimensions, typography, colors by role, borders, radii, shadows, spacing, alignment, visible states, responsive changes, source locations, and uncertain details. Finish with reusable CSS or Tailwind v4 guidance.

Start with components that appear often and control the site's main actions. The best first group is navigation, primary and secondary buttons, text inputs, cards, tabs, badges, and the main content section pattern.

Then add components important to the site's purpose, such as pricing rows, search controls, tables, filters, feature grids, or media cards. You do not need to document every decorative element before building a useful first pass.

For each component, compare at least two occurrences when possible. Check whether padding, radius, border, shadow, typography, and alignment recur. Also record exceptions, since a featured card or promotional button may intentionally use a different treatment.

The captured Linear examples suggest a practical order: document shared dark surfaces, muted dividers, compact controls, cool accent, and typography first, then describe how those choices appear in page controls and content blocks. Finish with states you could not see, such as focus, hover, loading, or mobile menu behavior. Those are questions for verification, not details to invent.

---

Use a comparison table with one row per component occurrence and columns for location, variant, size, typography, surface, border, radius, shadow, spacing, alignment, and visible state. Put repeated values side by side and mark differences in a separate exception column.

For example, compare two cards by asking whether padding and radius match, whether surfaces use the same role, whether titles share the same weight and line height, and whether actions align to the same edge. Repeat the check for buttons and navigation items.

Review components in their full page context as well. A style that looks correct in a component sample may feel wrong when the surrounding section has different width, contrast, or spacing. Compare desktop and narrow layouts where available, paying attention to wrapping, stacking, and control width.

Finally, build a small test page with the extracted tokens and two or three representative components. If it feels inconsistent, adjust shared foundations first. Add a component-specific exception only when the captured evidence shows a real difference.
