Answer 2

您只需将输入字段类型设置为“数字”，即可自动为您添加增量和减量按钮。这是代码示例：

<input type="number" class="form-control" id="input1" placeholder="enter amount">

Answer 3

您必须为btn和input-number类提供样式：

.btn{
  height: 50px;
  width: 50px;
  border-radius: 50%,
  background-color: #ccc;
}
.btn .glyphicon {
  color: #fff;
}

.input-number {
  margin: 0 15px;
  width: 50px !important;
  border: none;
}
.input-number: after {
  content: '';
  position: absolute;
  bottom: 0;
  height: 3px;
  width: 50px;
  background-color: #fff;
  left: 50% - 50px;
}

Answer 4

input.btneg {
  border-radius: 5cm;
  width: 40px;
  position: relative;
  margin-right: -30px;
  height: 0.8cm;
}

input.btpos {
  border-radius: 5cm;
  width: 40px;
  position: relative;
  margin-left: -30px;
  height: 0.8cm;
}

<input type="button" class="btneg " value="-">
<input type="text" name="noq1" id="noq1" min="1" max="15" value="12">
<input type="button" class="btpos " value="+">
