Pure.CSS has several special classes to create a responsive design.

Sr.No. Class Name & Description
1

.pure-u-*

Sets the container to occupy required space on any device.
2

.pure-u-sm-*

Sets the container to occupy required space on a device with width ≥ 568px.
3

.pure-u-md-*

Sets the container to occupy required space on a device with width ≥ 768px.
4

.pure-u-lg-*

Sets the container to occupy required space on a device with width ≥ 1024px.

5

.pure-u-xl-*

Sets the container to occupy required space on a device with width ≥ 1280px.

In the following example, we're going to create a responsive grid with a row having four columns. The columns should stack on small screens, should take up width: 50% on medium-sized screens, and should take up width: 25% on large screens.

This is done by adding .pure-u-1 class for small screens, .pure-u-md-1-2 for mediumsized screens, and .pure-u-lg-1-4 for large screens. Resize the page to see the grid response to the screen size.
