    <style>
.bigmodal {
  height: 90%;
  left: 5%;
  margin: 0;
  width: 90%;
}

.bigmodal.fade.in {
  top: 5%;
}

.bigmodal .modal-body {
  max-height: none;
}

.bigmodal .modal-content {
  width: 100%;
}

</style>

<a data-toggle="modal" href="#HoastedModal" class="btn btn-info">Hoasted Modal</a>

在大多数分辨率下都可以正常工作，但在某些分辨率下，存在下图所示的对齐问题：

该屏幕截图取自1613px的屏幕。
但是，如果我将屏幕缩小或放大一些，则对齐问题会得到解决：

Answer 1

由于您的“复选框”无法缩放，因此您可以在列表项中添加更多填充，并让图标位于填充中，以使左侧的文本不会在任何断点处发生干扰：

.list-group-item {
    padding-right: 40px;
}
.list-group-item i {
    position: absolute;
    right: 15px;
}
