在移动设备上查看自定义CSS复选框边距丢失

Question

我有一个用CSS编写的自定义复选框，在开发过程中看起来像预期的那样。但是当它在移动设备上观看时（通过Heroku），右边距不会出现，如下所示：

知道为什么在CSS中正确设置右边距时会消失？

自定义复选框CSS：

input[type="checkbox"],
.checkbox input[type="checkbox"],
.checkbox-inline input[type="checkbox"] {
  position: relative;
  border: none;
  margin-bottom: -4px;
  -webkit-appearance: none;
  appearance: none;
  cursor: pointer;
}
input[type="checkbox"]:focus,
.checkbox input[type="checkbox"]:focus,
.checkbox-inline input[type="checkbox"]:focus {
  outline: none;
}
input[type="checkbox"]:after,
.checkbox input[type="checkbox"]:after,
.checkbox-inline input[type="checkbox"]:after {
  content: "";
  display: block;
  width: 18px;
  height: 18px;
  margin-top: -2px;
  margin-right: 1rem;
  border: 2px solid #8D8D8D;
  border-radius: 4px;
  -webkit-transition: 240ms;
  -o-transition: 240ms;
  transition: 240ms;
}
input[type="checkbox"]:checked:before,
.checkbox input[type="checkbox"]:checked:before,
.checkbox-inline input[type="checkbox"]:checked:before {
  content: "";
  position: absolute;
  top: 0;
  left: 6px;
  display: table;
  width: 6px;
  height: 12px;
  border: 2px solid #fff;
  border-top-width: 0;
  border-left-width: 0;
  -webkit-transform: rotate(45deg);
  -ms-transform: rotate(45deg);
  -o-transform: rotate(45deg);
  transform: rotate(45deg);
}
input[type="checkbox"]:checked:after,
.checkbox input[type="checkbox"]:checked:after,
.checkbox-inline input[type="checkbox"]:checked:after {
  background-color: #00B1FF;
  border-color: #00B1FF;
}
input[type="checkbox"]:disabled:after,

}

.checkbox input[type="checkbox"]:disabled:checked:after,
.checkbox-inline input[type="checkbox"]:disabled:checked:after {
  background-color: #DFDFDF;
  border-color: transparent;
}
.has-warning input:not([type=checkbox]),
.has-warning .form-control,
.has-warning input.form-control[readonly],
.has-warning input[type=text][readonly],
.has-warning [type=text].form-control[readonly],
.has-warning input:not([type=checkbox]):focus,
.has-warning .form-control:focus {
  border-bottom: none;
  -webkit-box-shadow: inset 0 -2px 0 #FFD200;
  box-shadow: inset 0 -2px 0 #FFD200;
}
.has-error input:not([type=checkbox]),
.has-error .form-control,
.has-error input.form-control[readonly],
.has-error input[type=text][readonly],
.has-error [type=text].form-control[readonly],
.has-error input:not([type=checkbox]):focus,
.has-error .form-control:focus {
  border-bottom: none;
  -webkit-box-shadow: inset 0 -2px 0 #FF193C;
  box-shadow: inset 0 -2px 0 #FF193C;
}
.has-success input:not([type=checkbox]),
.has-success .form-control,
.has-success input.form-control[readonly],

}
.has-warning .input-group-addon,
.has-error .input-group-addon,
.has-success .input-group-addon {
  color: #F8F8F8;

}

Answer 1

我的朋友提供了答案。关键是移动线：

margin-right: 1rem;

到第一个街区：

input[type="checkbox"],
.checkbox input[type="checkbox"],
.checkbox-inline input[type="checkbox"] {
  position: relative;
  border: none;
  margin-bottom: -4px;
  margin-right: 1rem;
  -webkit-appearance: none;
  appearance: none;
  cursor: pointer;
}

我还将display: table更改为display: block。

现在一切看起来都很理想。
