Documentation
Primer’s layout includes basic page containers and a single-tiered, fraction-based grid system. That sounds more complicated than it really is though—it’s just containers, rows, and columns.
You can find all the below styles in _layout.scss.
Container
Center your page’s contents with a .container.
```html title=”Container”
The container applies `width: 980px;` and uses horizontal `margin`s to center it.
#### Grid
##### How it works
The grid is pretty standard—you create rows with `.columns` and individual columns with a column class and fraction class. Here's how it works:
- Add a `.container` to encapsulate everything and provide ample horizontal gutter space.
- Create your outer row to clear the floated columns with `<div class="columns">`.
- Add your columns with individual `<div class="column">`s.
- Add your fractional width classes to set the width of the columns (e.g., `.one-fourth`).
##### Demo
In practice, your columns will look like the example below.
```html title="Grid columns"
<div class="container">
<div class="columns mb-1">
<div class="one-fifth column block-blue p-3 border">
.one-fifth
</div>
<div class="four-fifths column block-blue p-3 border">
.four-fifths
</div>
</div>
<div class="columns mb-1">
<div class="one-fourth column block-blue p-3 border">
.one-fourth
</div>
<div class="three-fourths column block-blue p-3 border">
.three-fourths
</div>
</div>
<div class="columns mb-1">
<div class="one-third column block-blue p-3 border">
.one-third
</div>
<div class="two-thirds column block-blue p-3 border">
.two-thirds
</div>
</div>
<div class="columns">
<div class="one-half column block-blue p-3 border">
.one-half
</div>
<div class="one-half column block-blue p-3 border">
.one-half
</div>
</div>
</div>
Centered
Columns can be centered by adding .centered to the .column class.
```html title=”Grid centered”
```
