bootstrap栅格系统

容器：流体（container-fluid）、固定（container）
分12列，阈值分辨率>=1200,container固定尺寸为1170px，若阈值在992到1200之间container固定尺寸为970px，若分辨率在992以下778以上为750px，778px以下为自适应，没有固定的宽度值

分为12列，可根据列数确定，demo如下

不同分辨率下，设置col-lg表示超大分辨率，col-md是中等分辨率，col-sm是pad类似大小，col-xs是移动设备，如果设置了col-*那么会按照相应的分辨率显示，如果小于相应的分辨率则会变为几行，demo如下，可自行运行，以及对应demo图片

组合布局，可设置多个class，在分辨率为一个值得时候按照某个class显示，如果分辨率换成另外一个按照另外一个class显示，如下面demo所示，当分辨率大于1200时，按照col-lg显示四列，如果分辨率小于1200大于992，按照col-md显示三列
