FAQ – CSS Grid Placement

CSS Grid Placement is the method of positioning grid items inside a grid container using properties like grid-row-start, grid-row-end, grid-column-start, and grid-column-end. It allows you to build complex two‑dimensional layouts by placing items in specific cells, spanning multiple rows or columns, or even overlapping them.

Set your grid dimensions using the Columns, Rows, and Gap inputs at the top. Add items with the "Add Grid Item" button. Click any item to open the editor. There you can define exactly which rows and columns it should occupy, or clear the values to let the browser place it automatically.

auto lets the grid algorithm decide the start or end line. span (e.g., span 2) tells the item to stretch across that many tracks from its automatically placed position. You can enter numbers or span expressions directly in the editor fields.

This visual playground focuses on line‑based placement with numeric values. For production layouts, you can combine named lines and grid-template-areas. Our tool still lets you experiment with the fundamental placement logic that works with any grid definition.

Absolutely. The grid preview and editor stack on smaller screens so you can build and test responsive CSS grids even on phones and tablets. The layout automatically adapts to your viewport width.
