Pure.CSS Responsive Design

PURE.CSS has several special classes to create a responsive design.
S.N.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 devices with width ≥ 568px.
3.pure-u-md-*
Sets the container to occupy required space on a devices with width ≥ 768px.
4.pure-u-lg-*
Sets the container to occupy required space on a devices with width ≥ 1024px.
5.pure-u-xl-*
Sets the container to occupy required space on a devices with width ≥ 1280px.
In below example, we're going to create a responsive grid with a row with 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 the .pure-u-1 class for small screens, .pure-u-md-1-2 for medium-sized screens, and .pure-u-lg-1-4 for large screens. Resize the page to see the grid respond to the screen size.
