Grid Elements

A grid layout consists of a parent element, with one or more child elements.

Example

<div class="grid-container">
  <div class="grid-item">1</div>
  <div class="grid-item">2</div>
  <div class="grid-item">3</div>
  <div class="grid-item">4</div>
  <div class="grid-item">5</div>
  <div class="grid-item">6</div>
  <div class="grid-item">7</div>
  <div class="grid-item">8</div>
  <div class="grid-item">9</div>
</div>

Display Property

An HTML element becomes a grid container when its display property is set to grid or inline-grid.

Example

.grid-container {
  display: grid;
}

Example

.grid-container {
  display: inline-grid;
}

All direct children of the grid container automatically become grid items.

Grid Columns

The vertical lines of grid items are called columns.

Grid Rows

The horizontal lines of grid items are called rows.

Grid Gaps

The spaces between each column/row are called gaps.

You can adjust the gap size by using one of the following properties:

  • column-gap
  • row-gap
  • gap

Example

The column-gap property sets the gap between the columns:

.grid-container {
  display: grid;
  column-gap: 50px;
}

Example

The row-gap property sets the gap between the rows:

.grid-container {
  display: grid;
  row-gap: 50px;
}

Example

The gap property is a shorthand property for the row-gap and the column-gap properties:

.grid-container {
  display: grid;
  gap: 50px 100px;
}

Example

The gap property can also be used to set both the row gap and the column gap in one value:

.grid-container {
  display: grid;
  gap: 50px;
}

Grid Lines

The lines between columns are called column lines.

The lines between rows are called row lines.

Refer to line numbers when placing a grid item in a grid container:

Example

Place a grid item at column line 1, and let it end on column line 3:

.item1 {
  grid-column-start: 1;
  grid-column-end: 3;
}

Example

Place a grid item at row line 1, and let it end on row line 3:

.item1 {
  grid-row-start: 1;
  grid-row-end: 3;
}
