Pure.CSS具有几个特殊的类来创建响应式设计。
| 序号 | 类名和描述 |
|---|---|
| 1 | .pure-u- * 设置容器以占用任何设备上的所需空间。 |
| 2 | .pure-u-sm- * 设置容器以占用宽度≥568px的设备上的所需空间。 |
| 3 | .pure-u-md- * 设置容器以占用宽度≥768px的设备上的所需空间。 |
| 4 | .pure-u-lg- * 设置容器以占用宽度≥1024px的设备上的所需空间。 |
| 5 | .pure-u-xl- * 设置容器以占用宽度≥1280px的设备上的所需空间。 |
在下面的示例中，我们将创建一个具有四列的行的响应式网格。列应堆叠在小屏幕上，应占据宽度：在中型屏幕上占50％，在宽屏幕上应占占25％。
这是通过为小屏幕添加.pure-u-1类，为中型屏幕添加.pure-u- md-1-2和为大屏幕添加.pure-u-lg-1-4来完成的。调整页面大小以查看网格对屏幕尺寸的响应。
