Pure.CSS网格
PURE.CSS提供pure网格概念有两种类型，pure-g，网格类和单元类，pure-u- *。以下是使用纯网格的规则。
单位宽度是分数。例如，纯的pure-u-1-2表示1/2或50％的宽度，pure-u-2-5表示2/5或40％的宽度等等。
pure网格的子元素（具有pure-g类的元素）必须使用pure-u或者pure-u-*类名。
所有内容应该是要正确呈现网格单元的一部分。
网格单元尺寸
pure网格配备了第五和第24单元两个尺寸。下面的图示示出了其中一些可以被附加到pure-ui-可用单位的例子。例如，创造50％的宽度的单元格，则可以使用一个CSS样式pure-ui-1-2。
