Table of Contents
<^>Repeat()<^> is a notation that you can use with the grid-template-columns and grid-template-rows properties to make your rules more concise and easier to understand when creating a large amount of columns or rows.
For example, let's say we have this definition for a grid container:
.container {
display: grid;
grid-gap: 10px 15px;
grid-template-columns: 1fr 2fr 1fr 2fr 1fr 2fr;
grid-template-rows: 100px auto 20% 100px auto 20px;
}
We can use the <^>repeat()<^> notation like this instead to simplify:
.container {
display: grid;
grid-gap: 10px 15px;
grid-template-columns: repeat(3, 1fr 2fr);
grid-template-rows: repeat(2, 100px auto 20%);
}
The first value passed to <^>repeat()<^> is the number of repetitions and the second value is the grid tracks to repeat.
Repeat() with named lines
You can also use repeat with named lines:
.container {
display: grid;
grid-auto-flow: column dense;
grid-template-columns: repeat(4, [col] 1fr);
grid-template-rows: repeat(5, [row] 150px);
}
Which is equivalent to the following long-form definition:
.container {
display: grid;
grid-auto-flow: column dense;
grid-template-columns:
[col] 1fr
[col] 1fr
[col] 1fr
[col] 1fr;
grid-template-rows:
[row] 150px
[row] 150px
[row] 150px
[row] 150px
[row] 150px;
}
—
Named grid lines at the end of repeat notations end up sharing the same line as the next starting name line. For examples, with this:
.container {
display: grid;
grid-auto-flow: column dense;
grid-template-columns: repeat(4, [col-start] 1fr [col-end]);
grid-template-rows: repeat(5, [row-start] 150px [row-end]);
}
We get this equivalent long-form definition:
.container {
display: grid;
grid-auto-flow: column dense;
grid-template-columns:
[col-start] 1fr
[col-end col-start] 1fr
[col-end col-start] 1fr
[col-end col-start] 1fr [col-end];
grid-template-rows:
[row-start] 150px
[row-end row-start] 150px
[row-end row-start] 150px
[row-end row-start] 150px
[row-end row-start] 150px [row-end];
}
