Naked CSS vs Inspect

Inspect adds a CSS-variables layer to Chrome's built-in inspector. Naked CSS resolves CSS variables too — and adds pixel distance measurement, flex/grid gap detection, and :hover / :active state simulation on top. Here's how the two compare for modern CSS workflows.

What is the Inspect Chrome extension?

Inspect (full name: “Inspect: CSS Variable Inspector & Copier”) is a free Chrome extension by peppertom that mimics Chrome's built-in DevTools inspector and adds a layer showing the CSS variables used to style the inspected element. Activate the extension, press Alt+S to toggle between inspect and paused modes, browse CSS properties, and click any variable to copy its value to your clipboard. Inspect launched in March 2022 and remains focused on the single task of CSS variable extraction. Naked CSS extends the same idea into a full design audit workflow with multi-element distance measurement, flex/grid gap detection, and interactive state simulation.

The short version

Inspect is a focused tool. Press Alt+S, hover an element, click a CSS property, and the underlying variable value lands in your clipboard. That's the whole loop. If your CSS workflow is “find which variable is producing this color and copy it,” Inspect does that one job cleanly. Naked CSS does the same CSS-variable resolution — but as one feature among many. It also measures pixel distances between elements, hatches flex and grid gaps with pixel labels, toggles :hover and :active states on selected elements, copies IMG URLs and SVG outerHTML, and shows a full layout panel for display, flex, and grid properties. If you only need variable extraction, Inspect is a single-purpose tool. If you need the audit toolkit, Naked CSS is the broader choice.

What Inspect got right

Inspect is a focused tool with a clean idea. The Alt+S keyboard toggle is fast and out of the way; the visual style mimics the native DevTools inspector closely enough that the muscle memory transfers. The “click a property to copy” UX is direct — no settings, no panels, just hover and copy.

For developers whose entire workflow is “find which CSS variable maps to this color and grab the value,” it does exactly that and nothing more. The 2022 last-update date and Manifest V2 origin aside, the underlying idea — exposing CSS variables in the inspector — is genuinely useful and influenced how Naked CSS surfaces tokens in its own UI.

What Naked CSS adds on top of Inspect

Pixel distance between elements

The biggest workflow Inspect doesn't cover. Click an element to lock it, hover any second element, and both horizontal and vertical pixel distances render on-page with labeled guide lines. This is the measurement a design audit needs — “how far is this button from the heading,” “does this padding match the Figma spec.”

Flex / grid gap detection

Naked CSS hatches and labels every flex and grid gap region with its pixel value. Inspect surfaces CSS variables for the inspected element but doesn't hatch the actual spacing between flex/grid children — which is where most modern-layout spacing bugs live.

Interactive state simulation

Toggle Default, Hover, and Active states for any selected element with a single click. Inspect the interactive styling without scripting it or moving your cursor over the element. Inspect doesn't do this — it shows the static computed style.

Padding, margin, and box-model visualization

Per-side labels for top / right / bottom / left padding and margin, with hatched overlays. Border-radius is surfaced per-corner. Inspect shows the values inside its variable panel; Naked CSS shows them directly on the element, sized to the actual rendered dimensions.

Active maintenance and Manifest V3

Naked CSS ships on Chrome's current extension platform (Manifest V3) and is in active development as of May 2026. Inspect's last Chrome Web Store update was March 2022 and it predates Manifest V3 — which may matter for organizations whose Chrome policy now requires V3 extensions.

When to reach for which tool

Reach for Inspect when…

  • Your only need is to extract a CSS variable from a single element and copy the value.
  • You're already comfortable with the Alt+S keyboard pattern.
  • You don't need gap detection, distance measurement, or state simulation.
  • Your Chrome policy allows Manifest V2 extensions (Inspect predates V3).

Reach for Naked CSS when…

  • You need CSS variable resolution and anything else (distance, gaps, states, layout panel).
  • You're doing a design audit and need to verify spacing tokens against the Figma spec.
  • You need to verify flex/grid gap values in an implementation.
  • You want to inspect :hover and :active states without writing JavaScript.
  • You need a Manifest V3 extension on actively-maintained code.

The honest answer: if you need both, Naked CSS covers Inspect's wedge plus everything else — there's no scenario where keeping both pinned helps a workflow that Naked CSS alone doesn't.

How to switch from Inspect to Naked CSS in 30 seconds

  1. 1Install Naked CSS from the Chrome Web Store — Add to Chrome. It's free and takes two clicks.
  2. 2Pin Naked CSS in your toolbar (optional — the keyboard shortcut works either way).
  3. 3On any page, press Cmd+I (Mac) or Ctrl+I (Windows / Linux) to toggle Naked CSS — the equivalent of Inspect's Alt+S.
  4. 4Hover any element. CSS variable names appear inline with every color value. Press C to copy any surfaced value to your clipboard.
  5. 5(Optional) Open the Naked CSS options page to rebind the toggle shortcut to Alt+S if Inspect's muscle memory is already wired in.
