The CSS Grid Layout Module offers a grid-based layout system, with rows and columns, making it easier to design web pages without having to use floats and positioning.
A grid layout consists of a parent element, with one or more child elements.
<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>
An HTML element becomes a grid container when its display property is set to grid or inline-grid.
.grid-container {
display: grid;
}
.grid-container {
display: inline-grid;
}
All direct children of the grid container automatically become grid items.
The vertical lines of grid items are called columns.
The horizontal lines of grid items are called rows.
The spaces between each column/row are called gaps.
You can adjust the gap size by using one of the following properties:
The column-gap property sets the gap between the columns:
.grid-container {
display: grid;
column-gap: 50px;
}
The row-gap property sets the gap between the rows:
.grid-container {
display: grid;
row-gap: 50px;
}
The gap property is a shorthand property for the row-gap and the column-gap properties:
.grid-container {
display: grid;
gap: 50px 100px;
}
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;
}
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:
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;
}
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;
}
