Ionic 4 卡片图像重叠

Question

我正在寻找在 Ionic 上可行的解决方案？我已经使用了 z-index 但没有任何反应。

Overlap Image on Ionic Card Content

Html

<ion-card>
  <ion-card-content>
     <ion-img src="./assets/img/pizza-manager.png"></ion-img>
         </ion-card-content>
         <ion-card-header>
            sample
         </ion-card-header>
</ion-card>

CSS

ion-card {
  position: relative;
  height:30vh;
  width: 50vw;
  z-index: -1;
}

ion-card-content {
  height: 70%;
  z-index: -1;
}

ion-img {
  height: 20vh;
  width: auto;
  z-index: 2;
  position: absolute;
  margin-top: -50px;
}

我的结果：

Answer 1

看起来溢出被隐藏了。

我删除了你的大部分代码，只是玩了一下溢出设置，它得到了你要找的东西：

//重叠-card.page.html

<ion-header>
  <ion-toolbar>
    <ion-title>overlapping-card</ion-title>
  </ion-toolbar>
</ion-header>

<ion-content>
  <br>
  <br>
  <br>
  <br>
  <ion-card>
    <ion-card-content>
      <ion-img src="./assets/pizza.png"></ion-img>
    </ion-card-content>
    <ion-card-header>
      sample
    </ion-card-header>
  </ion-card>
</ion-content>

//重叠-card.page.scss

ion-card{
    height:30vh;
    width: 50vw;
    overflow: visible;    
}
ion-card-content{
    height: 70%;
    overflow: visible;    
}
ion-img{
    height: 20vh;
    width: auto;
    margin-top: -75px;
}

注意：ion-img 没有高度，我得到了一些奇怪的效果，所以你一定要设置它。

page.html

<ion-card>
   <ion-card-header>
      sample
   </ion-card-header>
</ion-card>   

<ion-img src="../../assets/images/feature-bootstrap.png"></ion-img>

    width: 250px;

ion-card-content{

    z-index: -1;
  }
}
ion-img{

    position: absolute;
    top: 0;
    right: -6px;
}

请尝试此代码，这将帮助您解决问题。

ion-card.main-card{
  background: #D29034;
  border-radius: 4px 100px 10px 10px;
  max-width:500px;
  overflow: visible;
  margin-top: 80px;
}
.card-img{
  max-width:80px;
}
.card-main-content{
  background: #F3F0F1;
  border-radius: 4px 60px 10px 10px;
}
.card-amount{
  --background: transparent;
  --border-color: transparent;
  color: #fff;
}
.card-image-blk{
  --background: transparent;
  --border-color: transparent;
  margin-bottom: -30px;
  margin-top: -30px;
}
