What is a CSS transparency grid?

A CSS transparency grid, also known as a checkerboard pattern or alpha channel background, is a visual pattern used to display transparent or semi-transparent images and elements. The grid consists of alternating colored squares that create a checkerboard effect, making it easy to identify transparent areas in images, especially when working with PNG files, SVG graphics, or CSS with alpha channels. This pattern is commonly used in design software like Photoshop, GIMP, and web development tools.
