CSS grid-auto-flow Property

CSS grid-auto-flow Property

The CSS grid-auto-flow property decides how auto-placed items get inserted into the grid.

Syntax:

grid-auto-flow: row|column|dense|row dense|column dense;

row (default) – places items by filling each row.

column – places items by filling each column.

dense – place items to fill any holes in the grid.

row dense – places items by filling each row, and fill any holes in the grid.

column dense – places items by filling each column, and fill any holes in the grid.

Example:

<!DOCTYPE html>
<html>
<head>
<style>
.item3 { grid-column: auto / span 2; }

.grid-container {
  display: grid;
  grid-template-columns: auto auto auto;
  grid-template-rows: auto auto;
  grid-gap: 10px;
  background-color: #e9c46a;
  padding: 10px;
}

.grid-container > div {
  background-color: #f4a261;
  text-align: center;
  padding: 20px 0;
  font-size: 30px;
}
</style>
</head>
<body>

<h4>grid-auto-flow: row;</h4>
<div class="grid-container" style="grid-auto-flow: row;">
  <div class="item1">1</div>
  <div class="item2">2</div>
  <div class="item3">3</div>
  <div class="item4">4</div>
</div>
<h4>grid-auto-flow: row dense;</h4>
<div class="grid-container" style="grid-auto-flow: row dense;">
  <div class="item1">1</div>
  <div class="item2">2</div>
  <div class="item3">3</div>
  <div class="item4">4</div>
</div>

</body>
</html>
