Question

我致力于将图片居中并朝向头部。我想要的是将图片比标题高两倍。我有一个在另一个上面：

<header>
  <div class="container">
    <img src="my_logo2.png" alt="Logo" class="logo">
    <h1>Auto Service</h1>
  </div>
</header>

Exceção fatal: android.app.RemoteServiceException
Bad notification for startForeground: java.lang.ClassCastException: int[] 
cannot be cast to android.app.PendingInten

android.app.ActivityThread$H.handleMessage (ActivityThread.java:1644)
android.os.Handler.dispatchMessage (Handler.java:102)
android.os.Looper.loop (Looper.java:154)
android.app.ActivityThread.main (ActivityThread.java:6123)
java.lang.reflect.Method.invoke (Method.java)
com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run 
(ZygoteInit.java:867)
com.android.internal.os.ZygoteInit.main (ZygoteInit.java:757)

有人能解释我如何获得欲望结果吗？

Answer 2

您想将商品置于div的中心吗？

.container {
  text-align: center;
}

img, h1 {
  margin: auto;
}

以图片和标题为中心
