Can I actually edit CSS on a live website?

Yes. MiroMiro's Live CSS Inspector lets you change any CSS value - color, font, padding, border-radius, shadow, anything - and see the page update in real time. Edits are local to your browser, so the live site stays untouched.

Are my edits saved when I reload the page?

No, edits are visual previews in your current session. That's the point: experiment freely without affecting the site. When you're happy with a change, copy the value as code and paste it into your own project.

How is this different from editing in Chrome DevTools?

DevTools exposes raw computed styles in a nested DOM tree and editing means hunting through hundreds of cascading rules. MiroMiro shows only the values that actually affect the element, lets you change them with friendly inputs and color pickers, and gives you a one-click "copy as code" output. Way faster, no inspector tree gymnastics.

Can I copy my edited values as Tailwind classes?

Yes. After editing, you can copy the result as raw CSS or as Tailwind utility classes. For exporting an entire section as Tailwind code, see Inspect & Export.

What CSS properties can I edit?

Any computed property: colors, typography, spacing (margin, padding, gap), borders, border-radius, shadows, gradients, transforms, opacity, z-index, and more. Both individual values and shorthand declarations are supported.

Does live editing work on React, Vue, Framer or Webflow sites?

Yes. MiroMiro edits the rendered DOM directly, so framework doesn't matter. Tested daily on Stripe, Linear, Vercel, Apple, Notion, and 10,000+ other sites.

How is MiroMiro different from CSS Peeper?

CSS Peeper is read-only - it shows you values but you can't change them. MiroMiro is read AND write: inspect, edit live, preview the change on the real page, and copy the edited values as code. Plus you get asset extraction, SVG/Lottie download, design tokens, and section-to-code export in the same extension.

Is editing someone else's website legal?

Yes - your edits exist only in your browser session, exactly like using DevTools. You're not modifying the live site or affecting other visitors. Always respect copyright when shipping anything inspired by what you saw.

What is the CSS inspector?

MiroMiroのライブCSSインスペクターは、あらゆるWebサイトをサンドボックスに変えます。要素にホバーするだけで、カラー、フォント、スペーシング、ボーダー、シャドウ、グラデーションなど完全なCSSを即座に確認。値をその場で編集すると、ページがリアルタイムに更新されます。ボタンのパディング調整、ヒーローのカラー変更、フォントウェイトの増減、カード全体のリスタイルも可能。デザインが決まったら、編集後の値をクリーンなCSSまたはTailwindとしてワンクリックでコピーし、そのままコードベースに貼り付けられます。リロードすると編集が消えるChrome DevToolsや、読み取り専用のCSS Peeperとは異なり、MiroMiroはライブ編集・リアルタイムプレビュー・ワンクリックコードエクスポートを1つの拡張機能に統合しています。
