Responsive CSS Grid with auto-fit and minmax()

.grid-container {
  display: grid;
  /* auto-fit will expand items to fill available space if there are fewer items than max columns */
  /* auto-fill would maintain fixed column count, leaving empty space */
  grid-template-columns: repeat(auto-fit, minmax(200px, 1fr));
  gap: 20px; /* Space between grid items */
  padding: 20px;
}

.grid-item {
  background-color: #e0f2f7;
  border: 1px solid #a7d9ed;
  padding: 15px;
  text-align: center;
  min-height: 100px;
}

How it works: This powerful snippet creates a responsive grid where the number of columns adapts dynamically based on the viewport size. `repeat(auto-fit, minmax(200px, 1fr))` ensures each column is at least `200px` wide but can grow (`1fr`) to fill available space. `auto-fit` will allow items to stretch and consume any leftover space if there are fewer items than maximum possible columns, while `gap` provides consistent spacing between grid items.
