Alignment Inspector is a Chrome extension designed for visually inspecting the alignment of elements on any webpage. This tool is particularly useful for designers, developers, and QA testers who require precise layouts. Users can easily compare the center, left, right, top, and bottom edges of selected elements with live pixel measurements, ensuring that everything is perfectly aligned. Activation is straightforward, requiring just a click on the extension icon to begin the inspection process.

The extension features visual alignment guides that display vertical and horizontal lines through the centers and edges of elements. It allows for multi-element comparisons, enabling users to select up to 100 elements at once. Live measurements provide exact pixel differences for alignment, accompanied by hover previews for instant visual feedback. Additional functionalities include a draggable panel for the info display and keyboard shortcuts for efficient use.
