Web Content Inspector

Web Content Inspector is a Chrome browser extension that lets users inspect text properties, media dimensions, layout structure, spacing, and visual boundaries on any webpage without opening the complex browser developer console. It provides developers, designers, and content creators with instant visual insights into page elements with a single click.

The problem

Modern browsers’ developer tools are powerful but can be cumbersome and time-consuming for quick visual inspection tasks. Right-clicking and opening “Inspect Element” for every minor layout check slows down debugging and design iteration, especially during rapid prototyping or UI QA.

Project Overview

Project Goals

Provide a one-click visual inspector that overlays key metrics (font sizes, family, bounding boxes) without requiring users to open Chrome DevTools.

Display precise media dimensions and rendering sizes for images, videos, and SVGs so users can verify layout consistency and detect scaling or optimization issues.

Highlight layout details such as padding, margins, sections, and DOM structure with color-coded overlays, making spacing and structural inspection faster and more intuitive.

Approach & Tech Stack

The extension was built using Chrome Extensions Platform (Manifest V3), with front-end scripting in JavaScript to traverse the DOM and compute visual properties. Overlays are rendered dynamically on the page without interfering with click actions. Layout computations use real-time element metrics and bounding boxes, and all processing runs locally to respect user privacy.

Final Results

Web Content Inspector delivers a lightweight, privacy-first tool that provides real-time visual insights into web pages. Users can activate or deactivate it with a click; it respects browsing flow, updates responsively as the page changes, and visualizes information developers normally extract through complex DevTools workflows. The extension streamlines design debugging and mobile layout checks while minimizing disruption to the browsing experience.
