You can inspect a website's motion and interactions by recording what changes, what triggers the change, and whether the change helps the visitor understand or act. A useful review names the trigger, affected content, animated property, timing, control, and fallback instead of using vague labels such as smooth or dynamic.

## Build a trigger-to-result inventory

Review the page in order and make one row for each meaningful interaction:

| Trigger | What changes | Where | Purpose | Fallback |
|---|---|---|---|---|
| Page load | Opacity, position, or scale | Opening section | Establish hierarchy | Content remains visible |
| Scroll | Crop, panel position, or progress | Feature section | Connect movement to a story | Static layout keeps the explanation |
| Hover | Color, border, label, or preview | Card or navigation | Signal an interactive item | Focus and tap states show the same cue |
| Click | Video, gallery, drawer, or modal | Product or proof section | Reveal detail | Direct link or expanded content |
| Drag or swipe | Gallery position or comparison | Media component | Let visitors explore | Buttons or keyboard controls |

The important question is what becomes clearer because of the effect. If nothing changes in the visitor's understanding or action, classify it as decoration and consider its distraction, loading cost, and accessibility risk.

The examples below provide comparison prompts. Refero is described as video-led, while Pangram AI Detector, Bland, and Fin Apex are described as using captured video with illustration or product-oriented visuals. Use those observations to ask about timing, framing, and emphasis. They are reference notes, not verified behavior for every viewport or state.

## Inspect motion in a fixed order

First check the initial state. Is useful content visible before animation begins? Does the opening frame already show the headline, product, and CTA, or does the design depend on a delayed reveal? Note anything that starts hidden, moves from outside the viewport, or appears only after a delay.

Next check the trigger. Scroll slowly and quickly, reverse direction, hover with a pointer, use a keyboard, and tap on a narrow screen. Record whether the effect responds continuously or at a threshold. Check whether a second interaction reverses the first one cleanly.

Then name the animated property. Movement, scale, opacity, blur, crop, color, and height affect reading in different ways. Large movement can pull attention away from text. Opacity can make content seem missing. A changing crop can hide the subject. Height animation can make the page jump. Naming the property makes the recommendation specific.

Finally check timing and control. Record whether the response is instant, short, repeated, tied to scroll distance, or controlled by the visitor. For video, check autoplay, looping, pause behavior, sound, captions, poster frames, and whether the media remains meaningful when playback stops.

## Test the interaction as a visitor

Use four questions:

1. **Discover:** Is the interactive element recognizable before use?
2. **Understand:** Does the first response explain what changed?
3. **Control:** Can the visitor pause, reverse, skip, close, or continue?
4. **Recover:** Can the visitor reach the same content without the intended gesture?

Apply these questions to menus, carousels, tabs, accordions, video, comparison sliders, hover previews, and scroll-linked stories. A hover cue is weak if it has no touch or keyboard equivalent. A scroll animation is useful when each change matches the nearby explanation, but distracting when the page moves while the visitor is trying to read.

## Turn findings into a motion brief

For every effect worth adapting, write its purpose, trigger, change, timing, visitor control, reduced-motion version, mobile version, and failure state. Compare the static and animated states. If the static state is confusing, the animation is probably hiding a content problem. If the static state is clear and motion adds timing, comparison, or feedback, it is more likely to be useful.

End with three recommendations: one pattern to keep, one to test, and one to avoid. Tie each to a visitor task and state whether it was observed or recommended. Fudge lets you help inspect captured page structure and state alongside motion, interactions, overlays, clipping, video, images, typography, and component styling. Treat the result as an observed reference, not a guarantee about the original site's private rules.

## Use this in your AI agent

> Inspect the captured website's motion and interactions in page order. For each meaningful effect, return the trigger, affected element, animated property, timing or repetition, visitor purpose, discoverability cue, keyboard or touch consideration, reduced-motion fallback, mobile fallback, and any content that remains available without the effect. End with a motion brief for the three most useful patterns, separating observed behavior from recommendations.

Describe the visitor's task before describing the effect. If the interaction reveals a product step, compares two states, shows where to continue, or provides supporting detail, it has a clear job. If removing it leaves the same meaning, classify it as decorative and test whether the emphasis justifies its cost.

A useful interaction should be recognizable, understandable, controllable when needed, and available through another path. For example, a hover preview needs a touch or keyboard equivalent. A scroll-linked product animation works best when each change matches the explanation beside it. Compare the static and animated states. If the static state is confusing, fix the content before adding motion. If the static state is clear and motion adds timing, comparison, or feedback, the effect is more likely to help.

For scroll effects, record the section start and end, the scroll distance, what moves or changes, and whether content stays readable. Note pinned panels, changing crops, fades, progress indicators, pauses, and jumps. Reverse the scroll to check consistency.

For hover states, record the default appearance, visual cue, focus state, tap behavior, and click result. Pay attention to labels or controls that appear only on hover. The same information should be available without a pointer.

For video controls, record the poster frame, autoplay behavior, sound state, loop point, pause and replay controls, captions, loading state, and what appears when playback is blocked. Also state whether the video is essential or supporting. These notes support specific recommendations such as a stronger poster frame, visible captions, a shorter loop, or an always-visible label.
