Question

我目前正在开展一个学校项目。 please click HERE to see my page

我有3瓶图像，我喜欢可点击，所以如果我点击一个瓶子，它会将我重定向到div。

这是我的html的样子：

.zero {
  height: 20%;
  background-color: #f8f5f2;
  color: 000b29;
  text-align: center;
  font-size: 80px;
}

.secOne {
  background-image: url("../img/hero/premium.jpg");
}

.sub_sectionOne {
  height: 20%;
  background-color: #000B29;
  color: #d70026;
  text-align: center;
  font-size: 80px;
}

.secTwo {
  background-image: url("../img/hero/black.jpg");
}

.sub_sectionTwo {
  height: 20%;
  background-color: #D70026;
  color: #f8f5f2;
  text-align: center;
  font-size: 80px;
}

.secThree {
  background-image: url("../img/hero/goldhero.jpg");
}

.sub_sectionThree {
  height: 20%;
  background-color: #edb83d;
  color: #d70026;
  text-align: center;
  font-size: 80px;
}

<div class="section">
  <video id="bgvid" autoplay loop poster="img/Snapshot/Beach-Ball.jpg" alt="people playing soccer at the beach">
       <source src="img/Mp4/Beach-Ball.mp4" type="video/mp4" />
       <source src="img/Ogv/Beach-Ball.ogv" type="video/ogv" />
       <source src="img/Webm/Beach-Ball.webm" type="video/webm" />
   </video>
  <!-- bottle navigation -->
  <div class="bottle">
    <h1>Beast Mode On</h1>
    <div class="bottle-nav">
      <img src="img/bottles/125_bluelightningbottle.png" alt="Oztonic Premium Energy Drink Bottle">
      <img src="img/bottles/125_redlightningbottle.png" alt="OzTonic Black Energy Drink Bottle">
      <img src="img/bottles/125_yellowlightningbottle.png" alt="OzTonic Gold Energy Drink Bottle">
    </div>
  </div>
  <!-- sections -->
  <div class="zero">
    <h2>Which Beast Are You?</h2>
  </div>
  <div class="section secOne"></div>
  <div class="sub_sectionOne">
    <h2>I'm a Premium Beast</h2>
  </div>
  <div class="section secTwo"></div>
  <div class="sub_sectionTwo">
    <h2>I'm a Black Beast</h2>
  </div>
  <div class="section secThree"></div>
  <div class="sub_sectionThree">
    <h2>I'm a Gold Beast</h2>
  </div>

所以我想让我的125_bluelightningbottle.png重定向到我 div class =“section secOne。我的125_redlightningbottle.png将我重定向到 div class =“section secTwo。和我的125_yellowlightningbottle.png将我重定向到div class =”section secThree。

带有类的div被这些样式设置（请参阅下面的css代码），如您所见，我的图像被设置为background-img：url（“.. img / hero / black.jpg'）;以及等......

然而这是我尝试过的，我有一个问题：如果我使用并用它包装bottle.png并放入并包装我的div class =“section secOne”我的所有背景 - img都消失了。

提前感谢您的帮助

如果要在单击图像时重定向到div，可以使用锚点将每个图像包装在标记中，并在目标元素上添加id。

<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/root_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">

<android.support.v7.widget.RecyclerView
    android:id="@+id/recycler_view"
    android:layout_width="0dp"
    android:layout_height="0dp"
    app:layout_constraintBottom_toBottomOf="@+id/root_layout"
    app:layout_constraintLeft_toLeftOf="@+id/root_layout"
    app:layout_constraintRight_toRightOf="@+id/root_layout"
    app:layout_constraintTop_toTopOf="@+id/root_layout"/>

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:layout_constraintBottom_toBottomOf="@+id/root_layout"
    app:layout_constraintRight_toRightOf="@+id/root_layout"
    android:layout_margin="16dp"
/>

</android.support.constraint.ConstraintLayout>

然后，如果您点击<a href="#secOne"> <img src="img/bottles/125_bluelightningbottle.png" alt="Oztonic Premium Energy Drink Bottle"> </a> <div class="section secOne" id="secOne">Your Div</span>锚点，您将转到seOne元素。

Here's an explanation

public class DisableReferencePreservationContractResolver : DefaultContractResolver
{
    readonly HashSet<Type> types;

    public DisableReferencePreservationContractResolver(IEnumerable<Type> types)
    {
        this.types = new HashSet<Type>(types);
    }

    bool ContainsType(Type type)
    {
        return types.Contains(type);
        //return types.Any(t => t.IsAssignableFrom(type));
    }

    bool? GetIsReferenceOverride(Type type)
    {
        return ContainsType(type) ? false : (bool?)null;
    }

    protected override JsonContract CreateContract(Type objectType)
    {
        // Disable IsReference for this type of object
        var contract = base.CreateContract(objectType);
        contract.IsReference = contract.IsReference ?? GetIsReferenceOverride(objectType);
        return contract;
    }
}

用上面的html代码替换你的html代码。
