CSS Grid is a two-dimensional layout system that can simultaneously control the arrangement of rows and columns, suitable for building complex web layouts.

CSS Grid vs Flexbox — What's the difference?

Grid is a 2D layout (controls rows and columns simultaneously), Flexbox is a 1D layout (controls rows or columns in one direction).Grid is better for overall page layout, Flexbox is better for component-level arrangement.

How to Use the CSS Grid Generator

CSS Grid is one of the most powerful layout systems in modern web development, providing a two-dimensional layout model that simultaneously controls the arrangement of rows and columns. Unlike Flexbox (a one-dimensional system), Grid lets developers create complex page layouts — magazine-style layouts, dashboard panels, image galleries, and more — without relying on outdated techniques like floats or positioning. Core Grid concepts include the grid container, grid item, grid line, and grid area, which together give you precise control over every element's position and size on the page. With our CSS Grid Generator, you can quickly create grid layouts through visual dragging and parameter adjustment, automatically generating CSS code compatible with all modern browsers.

Step 1

Set up the basic grid structure. First, define the number of columns and rows, along with their sizes. Column widths can use fixed pixel values (e.g., 200px), relative units (fr fractions), or a mix. For example, "1fr 2fr 1fr" creates a three-column layout where the middle column is twice as wide as the sides. You can also use the repeat() function to simplify repetitive definitions — repeat(3, 1fr) creates three equal columns. Row heights can be set to auto (content-based), fixed values, or minmax() for flexible responsive layouts with minimum and maximum height ranges.

Step 2

Configure grid gaps and alignment. Use the gap property to define spacing between grid items — you can set different values for row gaps and column gaps. For alignment, justify-items controls horizontal alignment of items within their cells, align-items controls vertical alignment, while justify-content and align-content control how the entire grid is positioned within the container. Common alignment values include start, end, center, and stretch. Proper alignment settings make your layout cleaner and more professional.

Step 3

Place grid items and export code. Click on grid cells to merge them into grid areas, or set individual items to span multiple rows and columns using grid-row and grid-column. Once your layout design is complete, the tool generates the corresponding CSS and HTML structure in real time. Copy the generated code into your project, making sure the parent element has display: grid. We also recommend adding media queries to adjust the number of columns and row heights at different screen sizes for a truly responsive design.

Q1: Should I use CSS Grid or Flexbox?

They're not mutually exclusive — they're complementary. Flexbox is best for one-dimensional layouts, such as navigation bars, button groups, or horizontal/vertical card lists. Grid is better suited for two-dimensional layouts, like overall page structure, dashboards, or image galleries where you need to control both rows and columns simultaneously. In practice, a common approach is to use Grid for the page's major framework, then use Flexbox within each area for component-level detail arrangements. Mastering both and using them flexibly is a fundamental skill in modern frontend development.

Q2: How do I create responsive layouts with CSS Grid?

The fr unit and auto-fill/auto-fit keywords are key to responsive Grid layouts. Using grid-template-columns: repeat(auto-fill, minmax(250px, 1fr)) creates auto-wrapping grid columns — as the container width changes, the number of columns adjusts automatically, with each column at a minimum of 250px and remaining space distributed equally. Combined with minmax(), this ensures content has reasonable display space at any screen size. You can also pair this with media queries to show more columns on large screens and fewer (or a single column) on small screens.

Q3: How is CSS Grid's browser compatibility?

CSS Grid has full support in all modern browsers (Chrome 57+, Firefox 52+, Safari 10.1+, Edge 16+), with a global browser support rate exceeding 97%. For projects that need IE11 support, note that IE11 uses the older Grid specification (-ms- prefix), and some features like grid-gap and auto-fill are not fully supported. If IE11 compatibility isn't needed, you can use standard Grid syntax directly without any prefixes. We recommend checking caniuse.com for the latest compatibility data.
