CSS Grid and Flexbox are the foundations of modern web layout, but they're invisible by default. You can't see grid lines, flex axes, or gap values just by looking at a page. Browser DevTools offer some grid overlay features, but they require you to find the container in the Elements panel first, enable the overlay manually, and only show one container at a time. Grid/Flex Visualizer automates this entirely — it scans the page, finds every Grid and Flex container, and renders their layout structure as visual overlays. Grid containers show column and row lines with track sizes labeled. Flex containers show the main axis direction, cross axis alignment, and how space is distributed. Gaps are highlighted with colored bands showing their pixel values. Click any container to see a detailed property panel with every layout property listed.
