缩略图大小缩略图中的缩略图缩放

Question

当我将鼠标悬停在拇指上时，我试图获得缩放效果，如此Codepen示例（第一个拇指，Lily效果）：

我修改了上面的示例以删除图形/ figcaption，并且我使用了一个用于拇指网格的flexbox布局，请参阅此笔：

.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，包括在拇指上设置尺寸，添加图形/图形 - 拇指刻度，但超出缩略图尺寸，这不是我想要的。

我开始怀疑可能是Flexbox布局导致缩放超出渲染的拇指大小，但我不确定。

有没有办法使用flexbox布局在渲染的拇指内进行缩放？

我认为您忘记了overflow:hidden：

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;
}

/*** LAYOUT ***/

.wrap {

  background-color: rgba(32, 38, 52, 0.6);
  background: #242B3A;
  font-family: "PT Sans", "Helvetica Neue", Arial, sans-serif;
  font-size: 100%;
  color: rgba(127, 133, 147, 0.8);
  border-radius: 5px;
  -webkit-border-radius: 0px 0px 5px 5px;
  -moz-border-radius: 0px 0px 5px 5px;
}

/*** GRID ***/

.row {

  margin: 6px 12px;
  overflow: hidden;
}

.row div img {
  width: 100%;
  height: auto;
  -webkit-backface-visibility: hidden;
  backface-visibility: hidden;
}


/*** EFFECTS ***/
.row img {

}

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

.row div:hover img {
