Features

CSS + Tailwind in one tool

Inspect any element. Get clean CSS and Tailwind output. Copy with one click.

Inspect

Hover & Click

Activate the inspector, hover any element — it highlights with tag name and dimensions. Click to capture all CSS properties instantly.

CSS

Clean output

Browser defaults removed. Shorthand collapsed. Pseudo-elements (::before, ::after) and :hover rules included. Media queries captured. CSS variables resolved.

Tailwind

Instant conversion

CSS properties mapped to Tailwind utility classes. Matched and arbitrary values shown separately. Unmatched properties listed so nothing is lost.

Inspect. Copy. Build.

Activate

Under the Hood

Every edge case handled

Pseudo-elements, media queries, CSS variables, shorthand collapse — all covered.

On-demand only

The inspector is NOT always-on. Injected only when you click Inspect, removed after capture. Zero impact on browsing.

Pseudo-elements

::before, ::after content and styles captured. :hover rules read directly from stylesheets via CSSOM.

Media queries

@media rules that apply to the element captured and shown separately. Responsive styles preserved.

CSS Variables

var(--custom-property) shown alongside resolved values. You see both the variable name and what it computes to.

Shorthand collapse

margin-top/right/bottom/left → margin. Longhand properties automatically collapsed into clean shorthands.

Inspection history

Last inspected elements saved as clickable tags. Click any to recall full CSS and Tailwind output.

Privacy

Runs only when you ask

OneClick CSS does not inject scripts on every page you visit. The inspector activates only when you click "Inspect Element" and is removed immediately after you capture an element.

No data is sent to any server. No accounts. No analytics. No cookies. The permissions are <all_urls> (so the inspector can run on any domain), scripting (inject on demand), and storage (save settings locally). There are no content_scripts in the manifest — nothing runs until you click.

FAQ

How much does OneClick CSS cost?

The core features are available at no cost. No accounts, no subscriptions required.

Does it run on every page I visit?

No. There are no content_scripts in the manifest. The inspector is injected only when you click "Inspect Element" and removed after capture. The <all_urls> permission is needed so chrome.scripting.executeScript() can run on any domain, but nothing executes until you ask.
