CSS Grid 网格布局
网格布局在二维画面里我认为还是非常好用的，所以我打算分享一下我对网格布局的粗浅认知，
所以我打算以一个简单地案例加以分析说明情况，
想了想，就用骰子吧，它的六个面很适合做一通详解
首先，当然是创建总体
然后稍稍分析写好结构，第一个因为只有一个点所以一个div,第二个有两个点所以两个div，第三个有三个点所以三个div。以此类推。
再接着写用到的用到的选择器，很容易知道我要用到六个盒子每个面有对应的点数自然也就写几个div
准备工作做好，然后开始书写再BOX中给长和宽以及边框，当然弄个圆角可以美化一下，
留出一点空间，然后转grid，接着经过分析:
父元素的设置-通过display:grid将盒子转成网格布局，在通过grid-template-columns和grid-template-rows将盒子设计成三行三列，
用grid-template-areas给每个区域赋予名号；
子元素的设置：因一点在中间，故而grid-area:a5,将div放到中间a5区域，
又因要居中所以在父容器加上justify-items：center以及align-items:center
第二面，当然就好书写了，首先面一样大，所以直接写，注意div
思考得知二点位置a1+a9
然后是三点位置a1+a5+a9
以此类推，书写好每个面得点数。ok这样我们就书写完成了
接下来给大家看一下全部布局、结构以及效果
