When the CSS Grid Generator seems to misbehave, the cause is usually one of two things: something stopped the tool from running, or it ran but the result is not usable. This guide starts with the fastest checks, then walks through the common problems and exact fixes.
Quick Checks First
- Refresh the page - a stalled session is the most common cause of nothing happening.
- Confirm the input is not empty and actually contains what you meant to submit.
- Try the smallest possible input; if that works, the issue is size, not the tool.
- Turn off browser extensions that block scripts, then reload and test again.
- Update or switch browsers if the problem repeats across sessions.
Common Problems and How to Fix Them
Items landed in the wrong cells.
Auto-placement fills holes in order - specify grid-column and grid-row when position matters.
My columns overflow the container.
Fixed pixel tracks add up too wide - switch to fr units so the tracks share the available space.
Rows collapse when content grows.
Let rows auto-size with auto or minmax(0, auto) instead of fixed heights.
Gap has no effect.
Gap only applies between tracks - check that you set it on the grid container, not on the items.
Named areas do not match the template.
Every area name must form a rectangle - fix mismatched quotes or stray cells in the template string.
The grid breaks on mobile.
Define different templates at breakpoints - responsive grids come from media queries around the container rule.
When It Works but the Output Is Poor
If the tool runs fine but the result misses, the problem is almost always the brief, not the software:
- Using grid for simple one-line alignment
- Hardcoding row heights that content overflows
- Forgetting auto rows for dynamic content
- Naming areas inconsistently with placements
How to Stop It Happening Next Time
- Keep a saved prompt template for every task you repeat.
- Change one setting per generation so causes stay obvious.
- Run a two-minute sanity test with known input after any update.
- Note every failure and its fix; a short troubleshooting log pays for itself.
Still Stuck?
Reproduce the problem with the smallest possible input and note the exact steps that triggered it. A one-line description of what you did, what you expected and what happened is enough to get a precise answer from support or a colleague.
Frequently Asked Questions
What are fr units?
A fraction of the leftover space - three 1fr columns share the container equally.
Can I define named areas?
Yes - the generator supports grid-template-areas alongside explicit line placement.
How do I make the grid responsive?
Generate a template per breakpoint and switch them in media queries - the tool outputs values you can reuse.
Is my layout saved?
No - everything runs in your browser, so copy the code before you leave.
