css - Bootstrap 4 响应式按钮大小

Question

Bootstrap 4 中有没有办法在 media-breakpoint-xs 中添加类“btn-sm”(小按钮)？

我希望按钮为默认大小，但在 xs 屏幕中我希望它们自动切换到 btn-sm。

Answer 1

使用 media-breakpoint-between mixin 为 .btn-sm 分配 .btn 大小...

/* change all .btn to .btn-sm size on xs */
@include media-breakpoint-between(xs,sm){
  .btn {
      @include button-size($btn-padding-y-sm, $btn-padding-x-sm, $font-size-sm, $btn-border-radius-sm);
  }
}

更新 - Bootstrap 4.1
此 button-size mixin 已略微更改为:

@include media-breakpoint-between(xs,sm){
  .btn {
      @include button-size($input-btn-padding-y-sm, $input-btn-padding-x-sm, $font-size-sm, $line-height-sm, $btn-border-radius-sm);
  }
}
