缩略图大小内的缩略图悬停缩放

Question

当我将鼠标悬停在拇指上时，我试图获得比例效果，就像在这个 Codepen 示例中一样（第一个拇指，百合效果）：

我修改了上面的例子，去掉了figure/figcaption，我为拇指网格使用了一个flexbox布局，看这支笔：

.row {
  display: flex;
  flex-flow: row wrap;
  padding: 0 5px;
  font-size: 0;
}

.row div {
  flex: auto;
  width: 160px;
  margin: 6px 12px;
}

.row div img {
  width: 100%;
  height: auto;
}


/*** EFFECTS ***/
.row img {
  position: relative;
  display: block;
  min-height: 100%;
  max-width: 100%;  
}

.row img {
  -webkit-transition: opacity 0.35s, -webkit-transform 0.35s;
  transition: opacity 0.35s, transform 0.35s;

}

.row:hover img {
  -webkit-transform: translate3d(0, 0, 0);
  transform: translate3d(0, 0, 0);
  -webkit-transform: scale(1.15);
  transform: scale(1.15);
}

我尝试了各种选项，包括在拇指上设置大小，添加图形/figcaption - 拇指比例，但超出了缩略图大小，这不是我想要的。

我开始怀疑可能是 flexbox 布局导致缩放超出了渲染的拇指大小，但我不确定。

有没有办法在渲染的拇指中使用 flexbox 布局进行缩放？

我想你忘记了overflow:hidden 的div：

.row div {
  flex: auto;
  width: 160px;
  margin: 6px 12px;
  overflow: hidden; 
}

html {
  box-sizing: border-box;
}

*,
*:before,
*:after {
  box-sizing: inherit;
}

ul {
  list-style-type: none;
}

a:link { text-decoration: none; } 
a:visited { text-decoration: none; } 
a:hover { text-decoration: none;}


html {
  background: #2b303b;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
}
