Hexo添加当前访客位置

JS

在 /source/js/custom.js 添加以下代码，点击申请一个key并填入提示位置，修改自己的经纬度

CSS

在 source/css/custom.css 原来的地方覆盖以下代码

#welcome-info {
    white-space: pre-wrap;
    border-radius: 14px;
    --kouseki-welcome-color: #49B1F5;
    --kouseki-ip-color: #49B1F5;
    --kouseki-gl-size: 16px!important;
}

引入

在主题配置文件_config.{themename}.yml里inject配置中的bottom引入jquery.min.js

inject:
  bottom:
    - <script type="text/javascript" src="https://unpkg.zhimg.com/jquery@latest/dist/jquery.min.js"></script> # jquery.min.js

在主题配置文件 _config.{themename}.yml下的inject配置项中的head引入custom.css

inject:
  head:
    - <link rel="stylesheet" href="/css/custom.css">

在aside配置项中修改

card_announcement:
  enable: true
  content: <div id="welcome-info"></div>
