Pricing cards with uneven content
Professional plan with the works
The full toolkit: priority rendering, team seats, and every integration we ship, including the ones still in beta.
Team
Shared workspaces and roles.
Subgrid ON: each card borrows the parent row tracks, so titles, bodies and buttons line up across cards no matter how long the text is.
Generated CSS
.pricing {
display: grid;
grid-template-columns: repeat(3, 1fr);
grid-template-rows: auto 1fr auto;
gap: 16px;
}
.pricing > .card {
display: grid;
grid-row: span 3;
grid-template-rows: subgrid; /* inherits the parent row tracks */
}About this tool
IconVault's CSS Subgrid lab makes the concept click in seconds. A row of pricing cards with deliberately uneven content renders twice in spirit: flip the switch and each card either sizes its own rows (buttons land at ragged heights) or inherits the parent tracks with grid-template-rows: subgrid (every title, body and button lines up). Row-track guides overlay the demo so you can see the shared tracks.
Adjust the column count and gap, then copy the generated CSS and HTML. It is free, runs fully in your browser, and subgrid is Baseline widely available (Chrome 117+, Firefox 71+, Safari 16+), so the code you copy works in production today.
