我想像附件中的图片一样制作屏幕，但遇到了一些问题。我的代码在小型设备和大型设备上运行良好，但在中型设备上运行不正常。所以任何人都可以查看我的代码并帮助我解决这个问题。实际上，我对 Flex 布局网格系统有点困惑。在 Bootstrap 中很容易实现这一点，但我希望在 Flex Layout 中也能做到这一点。

    <div fxLayout="row" fxLayout.sm="column" fxLayout.xs="column" fxLayoutAlign.lg="start center"
     fxLayoutAlign.xs="center center" fxLayoutAlign.sm="center center">

  <div fxFlex="25%" fxFlex.md="50%" fxFlex.sm="100%" fxFlex.xs="100%" fxLayout.md="row"
       class="pading_card">
    <mat-card class="example-card">
      <mat-card-header>
        <div mat-card-avatar class="example-header-image"></div>
        <mat-card-title>Shiba Inu</mat-card-title>
        <mat-card-subtitle>Dog Breed</mat-card-subtitle>
      </mat-card-header>

          The Shiba Inu is the smallest of the six original and distinct spitz breeds of dog from Japan.
          A small, agile dog that copes very well with mountainous terrain, the Shiba Inu was originally
          bred for hunting.
