### 🚀 Key Professional Features

#### 📏 High-Precision Element Inspection
Hover over any element on any webpage to instantly see its dimensions (width x height) and its exact position relative to the viewport. Locked selections provide deep-dive details including:
*   **Tag identity**: Tag names, IDs, and classes.
*   **Typography details**: Instant readout of font-size and font-family.
*   **Color Extraction**: Automatically identifies text colors, background colors, and border colors with visual swatches.
*   **Source Links**: Quick access to image or background-image URLs.

#### 📐 Adaptive Custom Selection
Need to measure the "white space" between elements? Use our Custom Selection tool. Simply click and drag anywhere on the screen to create a measurement bounding box. It’s perfect for checking gutters, margins, and arbitrary layout distances that the DOM won't tell you.

#### 🔄 Integrated Smart Converter
No more manual math or external calculator tabs. Our built-in unit converter works in real-time:
*   **Convert instantly**: Between Pixels (px), REM, EM, and Percentage (%).
*   **Standardized**: Calibrated to a 16px base font size for modern development standards.
*   **Contextual math**: Instantly see how a pixel value translates to a percentage of a 1000px container for quick layout prototyping.

#### 📜 Persistent Measurement History
Never lose a measurement again. Every element you "lock" or copy is automatically saved to your session History. 
*   **Quick Reference**: Revisit past dimensions even after you've moved to a different part of the page.
*   **Clean Workflow**: One-click "Clear History" to start fresh on a new project.

### 💎 Why Page Ruler Pro?

*   **Premium Aesthetics**: Features a modern "Glassmorphism" UI with frosted-glass effects, subtle gradients, and smooth animations that look stunning in both light and dark modes.
*   **Built for Speed**: Lightweight and lightning-fast. No bloat, no ads, and optimized for performance so it won't slow down your browser.
*   **Developer Friendly**: "Copy Info" button instantly formats all element specs into a clean layout ready to be pasted into your CSS, Jira tickets, or design hand-off documents.
*   **Context Menu Support**: Toggle the ruler with a simple right-click anywhere on the page.

*   Only requires the `activeTab` permission to provide measurement tools when you actually need them.
