按照Element UI官网文档写的表单，官网上输入文本框和下拉选择框长度是一致的，而我在没有更改相关样式的情况下，下拉选框却比文本框要短？

可以看到官网的下拉选择框是和输入框一致的宽度。

下面是我的单页代码：

<template>
  <div class="register-page">
    <section class="form-container">
      <div class="register-page-title">
        <span class="title">Yeoman在线后台管理系统</span>
      </div>
      <el-form class="register-form" status-icon :model="registerUser" :rules="rules" ref="registerForm" label-width="90px">
