grid-template-areas is a CSS Grid sub-property that lets you describe layouts using named areas like header, sidebar, main, and footer in an ASCII-art style format. Instead of using numeric row/column lines, you visually declare where each section goes. This approach is especially useful for page-level layouts where code readability matters. CSS automatically calculates position and size for each named area.
In grid-template-areas, cells span by repeating the area name across adjacent cells. For example, to make a header span the full width, write header in every column of the first row. To make a sidebar span two rows, write sidebar in the first column of both rows. This makes the template read like a visual map of your layout β the code looks like what it produces.
CSS Grid Layout including grid-template-areas is widely supported across all modern browsers: Chrome 57+ (March 2017), Firefox 52+ (March 2017), Safari 10.1+ (March 2017), and Edge 16+ (October 2017). The generated code uses standard CSS syntax. For legacy browser support (IE11), you would need additional fallbacks, but this tool generates standard-compliant CSS for modern browsers.
CSS Grid excels at two-dimensional layouts (both rows and columns simultaneously), making it ideal for page-level layout with header, sidebar, main content, and footer regions. Flexbox is best for one-dimensional layouts (single row or column) and is better suited for arranging elements inside components. They work great together: use Grid for the page skeleton and Flexbox for content arrangement within grid cells.
Yes, you can fully customize all Grid parameters. Column and row templates support all CSS values including px, fr, %, auto, min-content, max-content, and minmax(). The gap accepts any CSS length value. Changes are reflected in real-time in the visual preview. Each column and row can have different sizes β the template string is split by spaces and applied to each track.
