  style: css`
    .container {
      height: 200px;
    }

    .block {
      background: red;
      flex: 1;
    }
  `,
  modifiers: [...FlexLayout],
  template(this: HomeComponent) {
    return html`
      <div class="container" fxLayout="row" fxLayoutGap="10px">
        <div>
          <div class="block" fxLayoutAlign="center center" fxFlexFill>A</div>
        </div>
        <div>
          <div class="block" fxLayoutAlign="center center" fxFlexFill>B</div>
        </div>
        <div>
          <div class="block" fxLayoutAlign="center center" fxFlexFill>C</div>
