html - 如何在div下隐藏一个绝对位置的div

Question

我有两个 div 显示使用 flexbox 居中的“今日特别”菜肴。我想在第二道特色菜下多加一张图片。我认为它应该绝对定位，因为我可以从该部分的顶部推动它。我也尝试过使用 z-index，我想在第二道菜下放置占位符？如果它改变了一些东西，我会使用 sass。

这是代码：

.specials {
  background-image: url(../images/special-section-background.png);
  min-height: 440px;
  position: relative;
}

.specials .wrapper {
  position: absolute;
  text-align: center;
  width: 100%;
  height: 890px;
  padding-top: 30px;
}

.specials .wrapper .heading {
  font-family: "Playfair Display";
  color: #fff;
  font-size: 35px;
  font-weight: 700;
}

.specials .wrapper .images {
  display: -webkit-box;
  display: -ms-flexbox;
  display: flex;
  -webkit-box-pack: center;
      -ms-flex-pack: center;
          justify-content: center;
  -ms-flex-wrap: wrap;
      flex-wrap: wrap;
}

.specials .wrapper .images h2 {
  font-family: "Playfair Display";
  font-weight: 700;
  font-size: 26px;
}

.specials .wrapper .images p {
  font-family: "Sintony";
  font-size: 14px;
}

.specials .wrapper .images .contact {
  padding: 20px 0;
}

.specials .wrapper .images .contact h3,
.specials .wrapper .images .contact h4 {
  display: inline;
  padding: 0 20px;
}

.specials .wrapper .images .contact span {
  font-family: "Sintony";
  font-weight: 700;
  font-size: 13px;
  display: inline-block;
  text-align: start;
}

.specials .wrapper .images .contact span:after {
  content: '';
  height: 100%;
  width: 1px;
  border-right: 1px solid #e1e1e1;

  padding-top: 10px;
}

}

.specials .wrapper .images .first-dish .description {
  max-width: 430px;
  margin: 0 auto;
  padding-bottom: 30px;
  border-bottom: 1px solid #e1e1e1;

我做了两个改变：

• 添加position:relative到.images以提供位置上下文.last-offert
• 添加background:white到.second-dish. 以前它正确堆叠在占位符图像上方，但您无法分辨，因为背景是透明的。

我不确定我是否完全理解您的需求，所以如果我遗漏了什么，请告诉我。
