Question

我为产品包创建了以下代码。我需要中间框有一个红色背景，如果没有图像（用于CMS系统），我使用$('#button1').click(function() { $('.one').empty(); var toAdd = $('input[name=checkListItem]').val(); $('.one').html(toAdd); });，以便我可以垂直对齐图像，但这似乎是一个问题。它也需要半响应，因此基于％的宽度。我如何让中间的图像框有红色背景？

HTML：

display: table-cell

CSS：

<div class="category-products cf">
  <div class="cp-1">
    <div class="image">
      <img src="http://lorempixel.com/output/abstract-h-c-260-300-1.jpg" alt="">
    </div><!-- .image -->

    <div class="title">
      This Is A Product Title
    </div><!-- .title -->

    <div class="price">
      £10.99
    </div><!-- .price -->
  </div><!-- .cp-1 -->

  <div class="cp-2">
    <div class="image">

    </div><!-- .image -->

    <div class="title">
      This Is A Product Title
    </div><!-- .title -->

    <div class="price">
      £10.99
    </div><!-- .price -->
  </div><!-- .cp-2 -->

  <div class="cp-3">
    <div class="image">
      <img src="http://lorempixel.com/output/abstract-h-c-260-300-1.jpg" alt="">
    </div><!-- .image -->

    <div class="title">
      This Is A Product Title
    </div><!-- .title -->

    <div class="price">
      £10.99
    </div><!-- .price -->
  </div><!-- .cp-3 -->  
</div><!-- .category-products -->

Answer 1

使用display: flex代替display: table-cell（codepen）：

.image {
  display: flex;
  justify-content: center;
  align-items: center;
  height: 350px;
  border: 1px solid #b9b9b9;
  background: #fe0000;
}

Answer 2

您可以使用line-height并删除显示内容（显示：tabe-cell;为了正常工作，需要显示一个表/表行的父级）

单行上的行高将设置容器的最小高度。

div是块，它将达到100％宽度。

如果为空，则插入一个内联块伪元素以触发行高。

body {
  margin: 20px 0;
  font-family: sans-serif;
}
.category-products {
  width: 1000px;
  margin: auto;
}
.cp-1 {
  width: 32%;
  float: left;
  background: #999;
  text-align: center;
}
.cp-2 {
  width: 32%;
  float: left;
  background: #666;
  text-align: center;
  margin-left: 2%;
}
.cp-3 {
  width: 32%;
  float: left;
  background: #333;
  text-align: center;
  margin-left: 2%;
}
.image:before {
  content: '';
  display: inline-block;
}
.image {
  line-height: 350px;
  text-align: center;
  border: 1px solid #b9b9b9;
  background: #fe0000;
}
.image img {
  vertical-align: middle;
}
.title {
  font-size: 20px;
  line-height: 20px;
  padding: 12px 0;
  font-weight: bold;
}
.price {
  font-size: 18px;
}
