背景：产品提了一个需求在一个详情页，一个form表单元素太多了，需要滚动到最下面才能点击提交按钮，很不方便。他的方案是，加一个滚动条，这样可以直接拉到最下面。
优化：1、支持滚动条，这样方便快速往下拉2、点击提交按钮可以悬浮起来，这样随时都能修改完提交，不用拉到最底下。接下来就简单案例实现一下

直接用vue中的组件来实现这个小需求。

<!-- 滚动条 -->

    <el-form ref="formRef" :model="data" label-width="70px" size="mini"

<script>
export default {

}
</script>

<style>
.white{
  background: #fff;
  width: 100%;
  padding: 10px;
  border-radius: 5px;

  height: calc(100vh - 51px);
  overflow-x: hidden;
  overflow-y: scroll;

}
.white::-webkit-scrollbar {
  width: 10px;
  /*滚动条宽度*/
  height: 5px
  /*滚动条高度*/
}
/*定义滚动条轨道 内阴影+圆角*/
.white::-webkit-scrollbar-track {
  /*滚动条的背景区域的内阴影*/
  box-shadow: 0px 1px 3px rgba(0, 0, 0, 0) inset;

  /*滚动条的背景区域的圆角*/
  opacity: 0;
  /*滚动条的背景颜色*/
  background-color: rgba(0, 1, 0, 0);
}

/*定义滑块 内阴影+圆角*/
.white::-webkit-scrollbar-thumb {
  /*滚动条的内阴影*/
  box-shadow: 0px 1px 3px rgba(0, 0, 0, 0.3) inset;

  /*滚动条的圆角*/
  border-radius: 10px;

  /*滚动条的背景颜色*/
  background-color: #737871;
}
.formSubmit{
  width: 100%;
  padding: 20px;
  text-align: right;

  position: absolute;
  bottom: 50px;
  right: 20px;
}


</style>

最终实现的效果图如下。
右侧有下拉框、右下角固定住提交按钮即可
