The Most Powerful CSS Inspector for Web Developers

CSS Inspector transforms how you debug and understand CSS. Unlike browser DevTools, our inspector provides a cleaner, more focused experience with real-time visual overlays showing margins, padding, and element dimensions - all while hovering. Perfect for understanding complex layouts, debugging Tailwind CSS, and making quick style adjustments.

Key Features

Everything you need to inspect, understand, and edit CSS efficiently

Live Element Inspection

Hover over any element to instantly see its CSS rules, computed styles, and inheritance chain. Visual overlays show dimensions, margins, and padding in real-time as you move your cursor.

Visual Box Model Overlay

See the CSS box model come to life with color-coded overlays. Orange strips show margins, green strips show padding, and dimension labels appear automatically for each value - all without clicking.

Live CSS Editing

Click any CSS property value to edit it inline. Changes apply instantly to the page. Add new properties, rename existing ones, or remove them entirely - all with keyboard shortcuts for efficiency.

CSS Rule Discovery

View all CSS rules that match the selected element, sorted by specificity. See which stylesheet each rule comes from, identify overridden properties, and understand the cascade.

Tailwind CSS Support

Dedicated Tailwind tab automatically detects and categorizes Tailwind classes (layout, spacing, typography, colors, etc.). Toggle classes on/off, edit them inline, or add new ones with instant preview.

HTML Source View

Instantly view the clean HTML source of any element. One-click copy to clipboard, with internal inspector classes automatically filtered out for clean output.

Property Toggle & Disable

Quickly enable or disable individual CSS properties with checkboxes. Disabled properties use 'inherit' to properly override original values, letting you see the effect of removing specific styles.

Copy CSS Rules

Copy individual CSS rules or all styles for an element with one click. Output is formatted and ready to paste into your stylesheet, including inline styles, matched rules, and inherited styles.

Inherited Styles

View styles inherited from parent elements in a separate section. Understand which ancestor is providing typography settings, colors, or other inherited properties.

Crosshair Guidelines

Dashed crosshair lines extend from the hovered element to the viewport edges, with distance labels showing exactly how far the element is from each side of the window.

Dimension Badge

A floating badge shows the exact width and height of the hovered element in pixels, positioned near the element for quick reference without cluttering the view.

Computed Styles Fallback

When CSS rules can't be accessed (Tailwind, CSS-in-JS, cross-origin stylesheets), the inspector falls back to computed styles, ensuring you can always see what's actually applied.

Instant Feedback

See CSS changes apply immediately without refreshing. Perfect for rapid prototyping and debugging.

Draggable Panel

Position the inspector panel anywhere on screen. Resize it to fit your workflow.

Keyboard Shortcuts

Press Escape to stop inspecting. Enter to confirm edits. Tab to move between fields.
