CSS Grid Layout Module
This page is a copy from w3schools.com. Pictures are screenshots from the site. I made a copy because it's useful for me and hopefully may inspire someone to make their own webpage with this 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.
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;
}
Or
.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;
}
