How to Copy CSS From Any Website

Published August 11, 2026 · Updated August 11, 2026 · 7 min read · by the CSS DNA team

Quick answer: Right-click the element, choose Inspect, and copy the rules from the Styles panel. That gets you the authored base styles. To also capture :hover and :focus states, pseudo-elements, and values a framework computed at runtime, copy from computed styles instead — either through the DevTools Computed tab or a one-click extension like CSS DNA.

First: there are three different things people mean by “copy the CSS”

Most failed copy-pastes come from copying the wrong one. The distinction is worth 30 seconds:

• Authored CSS — what the developer typed. Contains variables, shorthand, media queries and comments. Readable, but incomplete for a single element.
• Computed CSS — the final value the browser resolved for every property after the cascade, inheritance and any math. This is what the element actually looks like right now.
• The component — the markup plus the styles for the element and everything inside it. This is what you need if you want the thing to work when you paste it.

If you want to learn a technique, copy authored CSS. If you want a value you can trust, copy computed CSS. If you want a working button, copy the component.

Method 1: DevTools Styles panel

1. Right-click the element and choose Inspect.
2. In the Styles pane, find the matching rule.
3. Right-click the selector and choose Copy rule (or Copy declarations).

Good for: understanding how something was built — you see the selector, the cascade order and which rules were overridden (struck through).

Breaks on: minified class names, values stored in custom properties, and anything the element only does on hover.

Method 2: DevTools Computed tab

With the element selected, switch to the Computed tab. Every property has a resolved value — var(--brand-600) becomes an actual color, 1em becomes pixels. In Chrome you can also right-click the element in the Elements tree and choose Copy → Copy styles to get the whole computed block at once.

Breaks on: volume. The computed list is hundreds of properties long, nearly all of them browser defaults, so you end up hand-filtering to find the dozen that matter.

Method 3: Save the page or read the source

Right-click → Save Page As… pulls down the HTML plus the stylesheets, images and scripts. Searching the source for @font-face, .woff2 or --color- is a fast way to find what a site loads.

Breaks on: modern sites. CSS-in-JS, atomic frameworks and build-time minification mean the file you download often has no readable relationship to what you saw on screen. It also tells you nothing about where a rule applies.

Method 4: Hover-to-copy extensions

A whole category of extensions puts a highlight box under your cursor and copies an element's CSS on click. This is the fastest path for “I just want that card's shadow.” Quality varies a lot in one specific way: whether the output is the raw computed dump or a cleaned, minimal rule you can actually paste.

Method 5: Capture the whole component, states included

If the goal is a working component rather than a value, you need four things the first four methods each miss part of: the markup, the element's own CSS, the CSS of its children, and its interaction states.

With CSS DNA:

1. Click the toolbar icon — no DevTools panel needed.
2. Click the element. Arrow keys walk up and down the DOM if you grabbed the wrong node.
3. Copy it as minimal CSS, full CSS, Tailwind classes, or a JSX style object.
4. Use pseudo-state capture to pull :hover, :focus, :active, ::before and ::after alongside the base rule.

Because it reads live computed styles, it does not care whether the site ships minified CSS, Tailwind utilities, or class names like .css-1x9f2kq.

The five methods, compared

The three things that silently break a copy-paste

1. Unresolved custom properties

You copy background: var(--surface-raised) and get transparent, because --surface-raised was defined on :root in a stylesheet you did not copy. Either copy computed values, or grab the site's variable block too.

2. Inherited values

font-family, line-height, color and letter-spacing are usually set once on body and inherited everywhere. They will not appear in the element's own rule, so the pasted component silently adopts your typography instead of theirs.

3. Missing layout context

A child of a flex or grid container behaves differently outside it. If the copied element used flex: 1 or grid-area, you also need the parent's display mode — or the layout collapses.

Copying computed styles solves the first two automatically. The third is why component capture, which brings the wrapper along, beats element-only copying.

Is copying CSS from a website legal?

Reading CSS is unavoidable — your browser downloads it to render the page, and inspecting it is ordinary practice. The line is between technique and expression:

• Fine: learning how a shadow, easing curve or grid was built, and using the same approach.
• Risky: lifting an entire stylesheet or reproducing a distinctive, recognizable design — that can implicate copyright or trade dress.
• Separate question: fonts, icons and images carry their own licenses. Identifying which font a site uses is free; using it may not be.

This is general information, not legal advice.
