CSS Grid Layout Module
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.
Grid Elements
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>
Display Property
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.
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
column-gap
property
The column-gap
property sets the gap between the columns:
.grid-container {
display: grid;
column-gap: 50px;
}
row-gap
property
The row-gap
property sets the gap between the rows:
.grid-container {
display: grid;
row-gap: 50px;
}
gap
property
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;
}
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.
Examples
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;
}
