在较小的设备上，如何使3个盒子相互叠放？

Question

嗨，我正在尝试创建3个盒子，旁边一个大两个小盒子，并在盒子内部添加图像。问题是在小型设备中，我希望3个盒子相互叠放而不是粘在上面彼此都喜欢，换句话说，他们没有反应。我正在研究这三天了，但我收不到。

.fashion_look img {
  width: 100%;
  display: inline;
  -webkit-transition: opacity 0.5s, -webkit-transform 0.5s;
  transition: opacity 0.5s, transform 0.5s;
}

.main-container .block-container .fashion_look .content {
  position: absolute;
  top: 5%;
  left: 0%;
  width: 100%;
  text-align: center;
  padding: 0 35px;
}

.main-container .block-container {
  display: inline-block;
  width: 100%;
  float: left;
}

.main-container .widget-static-block {
  display: block;
  overflow: hidden;
  padding-top: 60px;
}

.main-container .block-container .banner_top,
.main-container .block-container .new_shoes,
.main-container .block-container .fashion_look {
  position: relative;
  overflow: hidden;
}
