Flexbox容器问题，忽略宽度和高度

Question

我有下面的代码和以下问题：

图片容器应为正方形，并具有：

height: 5.5rem;
width: 5.5rem;

但不遵守此尺寸。

.slider {
  align-items: flex-start;
  display: flex;
  flex-direction: column;
}

.items {
  justify-content: center;
  margin: 0 auto;
  position: relative;
  display: flex;
}

.item {
  display: flex;
  flex-direction: row;
  left: 0;
  outline: 0;
  top: 0;
  opacity: 0;
  position: absolute;
  visibility: hidden;
  z-index: -1;
}

.item.show {
  position: relative;
  opacity: 1;
  visibility: visible;
  z-index: 9;
}

.image {
  height: 5.5rem;
  margin: 0 0.5rem 0 0;
  width: 5.5rem;
  align-items: center;
  padding: .5rem;
  display: flex;
  border: 1px solid black;
}

.image img {
  display: block;
  margin-left: auto;
  margin-right: auto;
  max-height: 100%;
  max-width: 100%;
}


}

我刚刚在.image中添加了flex-shrink:0;，它的工作原理是:)

.slider {
  align-items: flex-start;
  display: flex;
  flex-direction: column;
  }
  
.items { 
  justify-content: center;
  margin: 0 auto;
  position: relative;
  display: flex;
}

.item {
display: flex;
flex-direction: row;
left: 0;
outline: 0;
top: 0;
opacity: 0;
position: absolute;
visibility: hidden;
z-index: -1;
}

.item.show {
    position: relative;
    opacity: 1;
    visibility: visible;
    z-index: 9;
}

.image { 
height: 5.5rem;
margin: 0 0.5rem 0 0;
width: 5.5rem;
align-items: center;
padding: .5rem;
display:flex;
border: 1px solid black;
flex-shrink: 0;
}

.image img { 
    display: block;
    margin-left: auto;
    margin-right: auto;
    max-height: 100%;
    max-width: 100%;
}

}

<div class="slide">
  <div class="items">
    <div class="item show">
      <div class="image">
         <img src="https://via.placeholder.com/150">
       </div>
       <div class="content">Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of</div>
       </div>
 <div class="item">
      <div class="image">

如果您想要静态的宽度和高度，则可以设置 min 和 max 宽度和高度，因此：

.image {
  min-height: 5.5rem;
  min-width: 5.5rem;
  max-height: 5.5rem;
  max-width: 5.5rem;
}
