Html 图像库工作不正常

我有一个3个冒号x 4行画廊中12幅图像的未排序列表。 悬停时，将应用变换比例

   section#gallery{
          Width:670px;
    }
  section#gallery ul li{
display:inline;}
   section#gallery ul li img{
width: 215px;
height:150px;
border: 2px solid #fff;
margin: 5px 0px 0px 0px;

-webkit-transition: all 0.5s ease;
   -moz-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
   transition: all 0.5s ease;}

      }


     section#gallery ul li img:hover {

-webkit-transform:scale(2) ;
-moz-transform: scale(2);
-o-transform: scale(2);
-ms-transform: scale(2);
     transform: scale(2);
    -webkit-box-shadow:1px 1px 2px 1px  #999999;
    }

如何将（3n+1）图像（图像1-4-7-10）的变换原点设置为左侧 第三个（3-6-9-12）元素在右边

   section#gallery{
          Width:670px;
    }
  section#gallery ul li{
display:inline;}
   section#gallery ul li img{
width: 215px;
height:150px;
border: 2px solid #fff;
margin: 5px 0px 0px 0px;

-webkit-transition: all 0.5s ease;
   -moz-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
   transition: all 0.5s ease;}

      }


     section#gallery ul li img:hover {

-webkit-transform:scale(2) ;
-moz-transform: scale(2);
-o-transform: scale(2);
-ms-transform: scale(2);
     transform: scale(2);
    -webkit-box-shadow:1px 1px 2px 1px  #999999;
    }

我试图在这里输入html和css，但收到了错误消息。

您没有为变换原点指定所需的

y

值（因此我认为是

0

），但是如果您对图像应用比例，这应该会起作用（为特定供应商添加前缀）

   section#gallery{
          Width:670px;
    }
  section#gallery ul li{
display:inline;}
   section#gallery ul li img{
width: 215px;
height:150px;
border: 2px solid #fff;
margin: 5px 0px 0px 0px;

-webkit-transition: all 0.5s ease;
   -moz-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
   transition: all 0.5s ease;}

      }


     section#gallery ul li img:hover {

-webkit-transform:scale(2) ;
-moz-transform: scale(2);
-o-transform: scale(2);
-ms-transform: scale(2);
     transform: scale(2);
    -webkit-box-shadow:1px 1px 2px 1px  #999999;
    }

这是代码，我想如何通过css格式化它

   section#gallery{
          Width:670px;
    }
  section#gallery ul li{
display:inline;}
   section#gallery ul li img{
width: 215px;
height:150px;
border: 2px solid #fff;
margin: 5px 0px 0px 0px;

-webkit-transition: all 0.5s ease;
   -moz-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
   transition: all 0.5s ease;}

      }


     section#gallery ul li img:hover {

-webkit-transform:scale(2) ;
-moz-transform: scale(2);
-o-transform: scale(2);
-ms-transform: scale(2);
     transform: scale(2);
    -webkit-box-shadow:1px 1px 2px 1px  #999999;
    }

我在网站vsio.ru上放了一个草稿工作示例

   section#gallery{
          Width:670px;
    }
  section#gallery ul li{
display:inline;}
   section#gallery ul li img{
width: 215px;
height:150px;
border: 2px solid #fff;
margin: 5px 0px 0px 0px;

-webkit-transition: all 0.5s ease;
   -moz-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
   transition: all 0.5s ease;}

      }


     section#gallery ul li img:hover {

-webkit-transform:scale(2) ;
-moz-transform: scale(2);
-o-transform: scale(2);
-ms-transform: scale(2);
     transform: scale(2);
    -webkit-box-shadow:1px 1px 2px 1px  #999999;
    }

我要第四个七。。。。（3n+1）悬停时的图像要大2倍[tranform:scale（2）] 将变换原点集设置为左侧，将第三个第6个第9个……（3n）变换原点集设置为右侧

   section#gallery{
          Width:670px;
    }
  section#gallery ul li{
display:inline;}
   section#gallery ul li img{
width: 215px;
height:150px;
border: 2px solid #fff;
margin: 5px 0px 0px 0px;

-webkit-transition: all 0.5s ease;
   -moz-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
   transition: all 0.5s ease;}

      }


     section#gallery ul li img:hover {

-webkit-transform:scale(2) ;
-moz-transform: scale(2);
-o-transform: scale(2);
-ms-transform: scale(2);
     transform: scale(2);
    -webkit-box-shadow:1px 1px 2px 1px  #999999;
    }

（是否可能将伪类（HOVER）应用于伪元素（n-CHILD）？以及如何应用？）

   section#gallery{
          Width:670px;
    }
  section#gallery ul li{
display:inline;}
   section#gallery ul li img{
width: 215px;
height:150px;
border: 2px solid #fff;
margin: 5px 0px 0px 0px;

-webkit-transition: all 0.5s ease;
   -moz-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
   transition: all 0.5s ease;}

      }


     section#gallery ul li img:hover {

-webkit-transform:scale(2) ;
-moz-transform: scale(2);
-o-transform: scale(2);
-ms-transform: scale(2);
     transform: scale(2);
    -webkit-box-shadow:1px 1px 2px 1px  #999999;
    }

`

   section#gallery{
          Width:670px;
    }
  section#gallery ul li{
display:inline;}
   section#gallery ul li img{
width: 215px;
height:150px;
border: 2px solid #fff;
margin: 5px 0px 0px 0px;

-webkit-transition: all 0.5s ease;
   -moz-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
   transition: all 0.5s ease;}

      }


     section#gallery ul li img:hover {

-webkit-transform:scale(2) ;
-moz-transform: scale(2);
-o-transform: scale(2);
-ms-transform: scale(2);
     transform: scale(2);
    -webkit-box-shadow:1px 1px 2px 1px  #999999;
    }

问题解决了吗？

   section#gallery{
          Width:670px;
    }
  section#gallery ul li{
display:inline;}
   section#gallery ul li img{
width: 215px;
height:150px;
border: 2px solid #fff;
margin: 5px 0px 0px 0px;

-webkit-transition: all 0.5s ease;
   -moz-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
   transition: all 0.5s ease;}

      }


     section#gallery ul li img:hover {

-webkit-transform:scale(2) ;
-moz-transform: scale(2);
-o-transform: scale(2);
-ms-transform: scale(2);
     transform: scale(2);
    -webkit-box-shadow:1px 1px 2px 1px  #999999;
    }
