当鼠标悬停在图片上时效果

Question

如何创建以下悬停效果？

我试着这样做：

＆＃13;

＆＃13;

a.apparat {
  color: #4a4a4a;
}
a.apparat:hover{
  color: #1c97a9;
  text-decoration: none;
}
img.catalog_apparat {
  border: 2px solid #4a4a4a;
  width: 250px;
  height: 250px
}
img.catalog_apparat:hover {
  border: 2px solid #1c97a9;
}
.apparat_description {
  font-family: "Helvetica Neue",Helvetica,Arial,sans-serif;
  font-weight: bolder;
  font-size: 14px;
  margin:6px 0 10px;
  text-align: center;
}
.apparat_description:hover .catalog_apparat {
  border: 2px solid red;
}

＆＃13;

<a href="#" class="apparat">
  <img src="http://storage2.static.itmages.ru/i/16/0614/h_1465880975_7122477_d666884232.png" alt="Apparat 1" class="catalog_apparat">
  <div class="apparat_description">Gynecology</div>
</a>
