Bootstrap4更改断点

Question

尝试将lg的断点从默认值更改为1025：

@import "../scripts/bootstrap-4.1.1/scss/bootstrap";
$grid-breakpoints: (
  xs: 0,
  sm: 576px,
  md: 768px,
  lg: 1025px,
  xl: 1200px
);
$container-max-widths: (
  sm: 540px,
  md: 720px,
  lg: 993px,
  xl: 1140px
);

我希望在我的平板电脑上（横向模式下为1024px）将以下卡片2叠加在2而不是1以上4.这种改变似乎没有效果。
