How to use CSS Grid Generator
Set your grid structure using the controls on the left: choose the number of columns and rows, enter your template values (e.g., "1" for equal fractions, or "200px 1fr 200px" for a sidebar layout), and set the column and row gaps. Use the alignment dropdowns to control how items and content are distributed within the grid. The visual preview updates in real-time on the right. Switch between the CSS and HTML tabs to get the exact code to copy into your project.
Why use UtilDaily’s CSS Grid Generator?
- Writing CSS grid templates by hand requires memorizing property names and iterating blind — this visual generator collapses that iteration into a live preview with instant code output.
- Presets for Holy Grail, Card Grid, Sidebar, and 12-Column layouts give you a working starting point for the four most common real-world patterns.
- Outputs both CSS and HTML so you can drop the generated code directly into your project without any manual markup.
Frequently Asked Questions
What is CSS Grid and how does it work?
CSS Grid is a two-dimensional layout system that divides a container into rows and columns. You define the structure with grid-template-columns and grid-template-rows, then place child elements into the cells. The 'fr' unit (fraction) distributes available space proportionally — '1fr 2fr 1fr' creates three columns where the middle is twice as wide as the sides. Grid is ideal for page layouts, card grids, galleries, and any design that needs items aligned in both horizontal and vertical directions.
What is the difference between CSS Grid and Flexbox?
CSS Grid is two-dimensional (rows and columns simultaneously), while Flexbox is one-dimensional (either a row or a column). Use Grid when you need items to align in both directions — page layouts, card grids, calendar views. Use Flexbox for single-direction layouts — navigation bars, button groups, centering a single element. In practice, they complement each other: Grid for the overall page layout, Flexbox for components within each grid cell.
What does 'fr' mean in CSS Grid?
The 'fr' unit stands for 'fractional unit' and represents a portion of available space in the grid container. 'grid-template-columns: 1fr 1fr 1fr' creates three equal columns that together fill the container. '2fr 1fr' creates two columns where the first is twice as wide as the second. The fr unit is similar to flex-grow in Flexbox. It is calculated after fixed-size columns (px, em) and auto-sized columns are allocated space.
How do I make a responsive CSS grid?
Use auto-fill or auto-fit with minmax() for a responsive grid without media queries: grid-template-columns: repeat(auto-fill, minmax(250px, 1fr)). This creates as many columns as fit, each at least 250px wide and expanding to fill available space. auto-fill keeps empty grid cells; auto-fit collapses them. For simple responsive grids, combine this with a max-width container and gap for padding.
How do I center content in a CSS grid cell?
To center content within individual grid cells, use justify-items: center (horizontal) and align-items: center (vertical) on the grid container. For the entire grid content within its container, use justify-content: center and align-content: center. To center a single item without affecting others, use justify-self: center and align-self: center on that item. The alignment dropdowns in this generator handle all four properties.
