CSS Grid Generator Free Online Tool 2026

Grid vs. Flexbox

• Use Grid for two-dimensional layouts (rows AND columns)
• Use Flexbox for one-dimensional layouts (row OR column)
• Grid is better for page-level layouts and complex component grids
• Flexbox is better for navigation bars, button groups, and simple alignment
• They work great together — Grid for the outer layout, Flexbox for inner components

The CSS Grid Generator on TechConverter.me provides a visual interface for defining grid tracks, placing items, and configuring alignment. Design your layout visually and copy the generated CSS directly into your stylesheet.

/* Simple 3-column grid */
.grid-3col {
  display: grid;
  grid-template-columns: 1fr 1fr 1fr; /* or repeat(3, 1fr) */
  gap: 1.5rem;
}

/* Unequal columns */
.grid-sidebar {
  display: grid;
  grid-template-columns: 260px 1fr; /* fixed sidebar + flexible main */
  gap: 2rem;
}

/* Three columns with different proportions */
.grid-proportional {
  display: grid;
  grid-template-columns: 1fr 2fr 1fr; /* 25% | 50% | 25% */
  gap: 1rem;
}

/* Classic page layout with named areas */
.page-layout {
  display: grid;
  grid-template-areas:
    "header  header  header"
    "sidebar main    main"
    "sidebar main    main"
    "footer  footer  footer";
  grid-template-columns: 240px 1fr 1fr;
  grid-template-rows: 64px 1fr 1fr 80px;
  min-height: 100vh;
  gap: 0;
}

.page-header  { grid-area: header; }
.page-sidebar { grid-area: sidebar; }
.page-main    { grid-area: main; }
.page-footer  { grid-area: footer; }

/* Responsive: stack on mobile */
@media (max-width: 768px) {
  .page-layout {
    grid-template-areas:
      "header"
      "main"
      "sidebar"
      "footer";
    grid-template-columns: 1fr;
    grid-template-rows: auto;
  }
}

/* Auto-fill responsive grid */
.card-grid {
  display: grid;
  grid-template-columns: repeat(auto-fill, minmax(280px, 1fr));
  gap: 1.5rem;
}
/* Creates as many 280px+ columns as will fit.
   On a 1200px container: 4 columns (280px each)
   On a 900px container:  3 columns
   On a 600px container:  2 columns
   On a 320px container:  1 column
   No media queries needed! */

/* auto-fit vs auto-fill:
   auto-fill: keeps empty tracks (columns don't stretch to fill)
   auto-fit: collapses empty tracks (items stretch to fill row) */
.card-grid-stretch {
  grid-template-columns: repeat(auto-fit, minmax(280px, 1fr));
}
