Page Grid is a free Chrome extension developed by chYer that allows users to add an adjustable grid layout to any webpage. With this handy tool, you can easily draw a grid overlay on a webpage, making it easier to align and organize elements.

To use Page Grid, simply navigate to the webpage you want to work with and click on the toolbar button. Once activated, the toolbar icon turns blue, indicating that the extension is active. To deactivate it, simply click the toolbar button again, and the icon will turn gray.

Page Grid offers a range of customization options. You can adjust the grid's position (X/Y), line color, size, order (z-index), and line width (in pixels) through the extension's options page. If you want to remove the grid from the page, you can either reload the active tab or click the toolbar button again.
