这是一个登录界面的 HTML 代码，其中包含一个表单，表单中有用户名、密码、验证码等输入框和登录、注册按钮。登录按钮的点击事件会向服务器发送登录请求，注册按钮的点击事件则会跳转到注册页面。在样式上，页面使用了表格来布局，表格的中心位置放置了登录表单。

需要注意的是，该代码中使用了 JSP 内置对象 `pageContext`，其中的 `${pageContext.request.contextPath }` 表示获取当前应用的根路径。该路径将在登录界面中获取验证码的 Servlet 中使用。

你可以尝试在每个 `<el-col>` 元素中添加 `align="center"` 属性，同时在最外层的 `<el-row>` 元素中添加 `justify="center"` 属性，代码如下：

<el-row justify="center">
  <el-col :span="5" align="center">
    <el-card style="color:#409EFF">
      <div style="color:#409EFF"><i class="el-icon-s-shop"/>能力发布驳回数</div>
      <div style="padding:10px 0;text-align:center;font-weight:bold">100</div>
    </el-card>
  </el-col>
  <el-col :span="5" align="center">
    <el-card style="color:#409EFF">
      <div style="color:#409EFF"><i class="el-icon-s-shop"/>人工告警数量</div>
      <div style="padding:10px 0;text-align:center;font-weight:bold">100</div>
    </el-card>
  </el-col>
  <el-col :span="5" align="center">
    <el-card style="color:#409EFF">
      <div style="color:#409EFF"><i class="el-icon-s-shop"/>自动告警数量</div>
      <div style="padding:10px 0;text-align:center;font-weight:bold">100</div>
    </el-card>
  </el-col>
  <el-col :span="5" align="center">
    <el-card style="color:#409EFF">
      <div style="color:#409EFF"><i class="el-icon-s-shop"/>钉钉告警数量</div>
      <div style="padding:10px 0;text-align:center;font-weight:bold">100</div>
    </el-card>
  </el-col>
  <el-col :span="5" align="center">
    <el-card style="color:#409EFF">
      <div style="color:#409EFF"><i class="el-icon-s-shop"/>BOMC告警数量</div>
      <div style="padding:10px 0;text-align:center;font-weight:bold">100</div>
    </el-card>
  </el-col>
</el-row>

这样设置后，每个卡片的宽度会被限定在 `<el-col>` 元素的宽度内，同时 `<el-row>` 元素的 `justify` 属性可以让所有的元素在水平方向上居中对齐。
