CSS Grid Generator

CSS Grid is a two-dimensional layout system built into modern browsers that lets you define rows and columns simultaneously. Unlike Flexbox, which is one-dimensional, CSS Grid gives you precise control over both axes at once. You define a grid container with `display: grid`, then specify grid-template-columns and grid-template-rows to create tracks. Child elements are automatically placed into cells, or you can position them explicitly with `grid-column` and `grid-row`. Our css grid generator handles all of this configuration visually so you can focus on the layout rather than memorizing syntax.

1. 1. Configure Your Grid Tracks: Add columns and rows using the track inputs. Type any valid CSS track value — fr, px, %, auto, minmax(), or repeat(). Click a track input to see preset values like 1fr, 2fr, auto, and minmax(100px, 1fr). The live preview updates instantly as you type.
2. 2. Set Gap and Alignment: Configure column-gap and row-gap independently, then choose justify-items, align-items, justify-content, and align-content from the dropdowns. Optionally enable named template areas and type area names directly into the grid cells.
3. 3. Copy or Download the CSS: The generated CSS output updates in real time. Click Copy CSS to copy the complete .grid-container ruleset to your clipboard, or click Download to save it as a .css file. All processing happens locally in your browser — no data is sent to any server.

• grid-template-columns & grid-template-rows: The core track definitions for your grid. Supports any valid CSS track value including fr units, fixed lengths, percentages, auto, min-content, max-content, and minmax() functions.
• gap, column-gap, row-gap: When column-gap and row-gap are equal, the generator outputs the shorthand gap property. When they differ, it outputs column-gap and row-gap separately for maximum browser compatibility.
• justify-items, align-items, justify-content, align-content: Alignment properties that control how grid items and the grid itself are positioned within the container. Only non-default values are included in the output to keep the CSS clean.
• grid-template-areas: When named template areas are enabled, the generator outputs a grid-template-areas string with quoted row definitions. Use the same name across multiple cells to create spanning areas.

The most common track value is fr (fractional unit), which distributes available space proportionally — `1fr 2fr 1fr` gives the middle column twice the space. auto sizes the track to fit its content. px and % give fixed or percentage-based sizes. minmax(min, max) creates a responsive track that is at least `min` and at most `max` — `minmax(200px, 1fr)` is a common pattern for responsive columns. repeat(n, value) shorthand repeats a track definition — `repeat(3, 1fr)` is equivalent to `1fr 1fr 1fr`. auto-fill and auto-fit with minmax() create fully responsive grids without media queries.
