`X` must be an integer less than `Y`.

`Y` can be any of the following numbers: 2, 3, 4, 5, 6, 8, 10, 12.

### Plugins

Utilities that can be limited to specific Media Query breakpoints.

* `u-sm-sizeXofY` - To use at the smallest Media Query breakpoint.
* `u-md-sizeXofY` - To use at the medium Media Query breakpoint.
* `u-lg-sizeXofY` - To use at the largest Media Query breakpoint.

### Configuration

There are 3 Media Query breakpoints:

* `--sm-viewport`
* `--md-viewport`
* `--lg-viewport`

When using the [SUIT CSS preprocessor](https://github.com/suitcss/preprocessor),
breakpoints can be configured using `@custom-media`. For example:

```css
@custom-media --sm-viewport (min-width:320px) and (max-width:640px);
@custom-media --md-viewport (min-width:640px) and (max-width:960px);
@custom-media --lg-viewport (min-width:960px);
```
