前言

为博客的侧边栏添加一个欢迎语。本篇文章原教程来自 Kouseki 所发布的 在侧边栏添加个性定位欢迎信息

步骤

在 腾讯位置服务 中先创建应用，其中应用名称和 应用类型可以随意填写。然后点击添加Key，勾选WebServiceAPI。其中Key名称和描述可任意填写，添加后会生成一个 Key

这里面的白名单 localhost 是有效的，需带上端口号，记得填上自己域名

新建 welcome.js 文件，并粘贴如下代码：

在第6行及第32行分别填入自己的 Key 和 经纬度

新建 welcome.css 文件，并粘贴如下代码：

#welcome-info {

    --kouseki-ip-color: #49B1F5;
    --kouseki-gl-size: 16px!important;
  }

在主题配置文件 _config.anzhiyu.yml 中引入这两个文件
