1、设置前的代码

<el-form-item label="管理员密码" prop="password" >
          <el-input type="password" v-model="ruleForm.password" autocomplete="off"></el-input>
        </el-form-item>

2、修改后的代码

<el-form-item prop="name">
           <span slot="label">
             <span style="color: white"><strong>管理员账号</strong>      </span>
           </span>
        <el-input v-model="ruleForm.name"></el-input>
 </el-form-item>
