CSS Grid Generator: Build CSS Grid Layouts Visually Without Memorizing Syntax

What CSS Grid Generator Does and Who It Is For

CSS Grid is a two-dimensional layout system in CSS that lets you define rows and columns on a container and place children precisely within the resulting grid cells. The syntax covers grid-template-columns, grid-template-rows, grid-column, grid-row, and a range of shorthand and placement properties that take time to internalize.

CSS Grid Generator exists specifically because many developers find the syntax hard to approach. The README states the motivation directly: the author noticed that many people were not using Grid because they felt it was too complicated. The tool's purpose is to get people up and running quickly and into more interesting layouts.

The workflow is visual first. You set the number of columns and rows and their units (px, fr, auto, %, and so on). The generator draws the grid. You then drag across cells to define a div that spans a chosen area, and the tool records the placement. When you have the layout you want, you copy the generated CSS and HTML and paste them into your own project.

The target audience is front-end engineers new to CSS Grid, students learning layout, and experienced developers who want to prototype a grid structure without context-switching to write declarations from memory. The README recommends deeper resources by Rachel Andrew, Jen Simmons, and Dave Geddes for users who want to go further, along with the CSS Grid guide on CSS-Tricks and the Grid Garden game.

How the Generator Works Inside

The tool is built with Vue 2.6.10, Vuex 3 for state management, and vue-i18n 8 for internationalization. The view layer renders the grid configuration and the draggable placement area using Vue's reactivity system. Vuex holds the grid state: the column and row definitions and the list of placed div spans.

As you change column or row counts and units in the configuration panel, Vuex updates the state and Vue re-renders the grid. When you drag across cells, the selection is captured and added to the placed divs list in the store. The generated CSS and HTML output is derived from that store state at render time.

The package.json lists focus-trap as a dependency, which handles keyboard accessibility for modal interactions. The build system is Vue CLI 3 with Babel and sass-loader. Autoprefixer runs via PostCSS to add vendor prefixes to the generated CSS output.

The generator is available as a live tool at cssgrid-generator.netlify.com, hosted on Netlify. You do not need to install anything to use it.

Running the Project Locally

If you want to run the generator locally or contribute, the setup uses Yarn:

yarn install

Start the development server with hot reload:

yarn run serve

The dev server starts on a local port and watches source files for changes. To build for production:

yarn run build

To run the test suite:

yarn run test

To lint and auto-fix files:

yarn run lint

The tests use Jest. The build output is a static site that can be deployed to any static hosting service. The project is open to contributions; the README notes this explicitly. Configuration for the Vue CLI is in the Vue documentation reference at cli.vuejs.org/config/.

What the Generator Does and Does Not Cover

The generator handles the core use case well: defining a grid with explicit column and row tracks and placing named divs within it. The output CSS uses grid-template-columns, grid-template-rows, and grid-area or grid-column and grid-row declarations based on what you have dragged.

The README is clear about the scope: "this small generator only touches on a fraction of the features." CSS Grid has a large property surface including grid-template-areas, auto-placement, implicit grid tracks, named grid lines, minmax(), fit-content(), masonry-style layouts, subgrid, and alignment properties. None of these appear in the generator interface based on the README description.

This is an intentional scope choice, not an oversight. The README explicitly says the purpose is to get people up and running quickly, not to expose the full CSS Grid specification. For the complete feature set, users are directed to the external resources the README lists.

The vue-i18n dependency suggests the interface has been translated, or is set up for translation, which makes the tool accessible to non-English-speaking developers.

CSS Grid Generator vs Layoutit Grid

Layoutit Grid appears in the RELATED SEARCHES for this project, which indicates people compare the two tools. Layoutit Grid is a separate web tool that also generates CSS Grid code visually. The README for sdras/cssgridgenerator does not mention Layoutit Grid or document differences from it.

The clear difference in scope from the README is that sdras/cssgridgenerator is explicitly described as covering a fraction of CSS Grid features, targeting beginners who need a quick start. It is a focused, minimal tool with a single clearly stated purpose: reduce the barrier to entry for CSS Grid.

For engineers who already understand CSS Grid and want to prototype complex layouts with the full property set, both tools are worth evaluating. For someone learning CSS Grid for the first time, the minimal scope of this generator is a feature rather than a limitation; a simpler tool is less confusing as a starting point.

The generator is MIT-licensed, so the source is available to fork, modify, and use in any context.

Maintenance and Contributing

The last push to the main branch was on 2026-04-06. The repository has no GitHub releases; the live site at cssgrid-generator.netlify.com serves the current built version.

The project is open to contributions, which the README states directly. The contribution workflow follows the standard GitHub fork and pull request model. Before opening a pull request, run yarn run lint to check for code style issues and yarn run test to verify the test suite passes.

The Vue 2 dependency is worth noting for contributors: Vue 2 reached its end of life at the end of 2023 according to the Vue team. The package.json currently uses vue 2.6.10 and vue-cli-service 3. Upgrading to Vue 3 would be a substantial change that the repository has not yet made. Teams evaluating whether to build on this codebase should factor in the Vue 2 dependency as a maintenance consideration.

Editorial conclusion

CSS Grid Generator is useful for engineers and designers who are getting started with CSS Grid and want to see the relationship between the grid definition and the resulting layout before writing any code. It is not a full grid authoring environment; it covers basic grid definitions and does not expose the full CSS Grid property set. The last push to the main branch was on 2026-04-06. Before contributing, run yarn install, start the dev server with yarn run serve, and test with yarn run test.
