使用说明（下面三种效果任选其一）：
效果1：编辑K Blue风格文件夹的g.css，在最下面加入 css片段1+css片段2+css片段4。默认背景是比较亮的圆组成，鼠标移动到页面上，背景里的圆变暗（既是本页效果）。
效果2：复制css片段1+css片段2，在g.css的最下面加入。效果：背景圆一直都是亮色的，鼠标移动到页面无变化。
效果3：复制css片段2+css片段3，在g.css的最下面加入。效果：背景圆一直都是暗色的，鼠标移动到页面无变化。
K Blue G2是K Blue的一个小分支，想使用G2风格只需按照上面的步骤修改css文件即可。
Ps:K Blue、K Blue G1、K Blue G2的区别：
K Blue ：基础简洁版，背景色是灰色的过度，背景无彩色圆。
K Blue G1 ： 跟"K Blue"类似，背景色加上了26个彩色的圆。
K Blue G2 ： 暗色调，背景色是黑色加上了26个彩色的圆。
