}

.github-badge .bg-orange { 
  background-color: #ffa500
}

}

.github-badge .bg-green {

  background-color: #ab34e9
}

2.将以下内容添加至开发者设置-博客底部左侧信息,将内容改成自己的

<div class="github-badge">
<a href="./" title="©2019&nbsp;Alvin">
<span class="badge-subject">Copyright</span><span class="badge-value bg-blue">©2019&nbsp;Alvin</span>
</a>
</div>
&nbsp;|&nbsp;
<div class="github-badge">
<a href="http://www.miitbeian.gov.cn/" target="_blank" title="粤ICP备 xxx号" style="cursor: url(&quot;/usr/plugins/HoerMouse/static/image/dew/link.cur&quot;), pointer;">
<span class="badge-subject">粤ICP备</span><span class="badge-value bg-green">xxx号</span>
</a>
</div>

3.将以下内容添加至开发者设置-博客底部右侧信息

<div class="github-badge">

<span class="badge-subject">Theme</span><span class="badge-value bg-orange">Handsome</span>
</a>

4.修改handsomecomponentfooter.php文件

删除代码以下代码（大概第八行左右）：

Powered by <a target="blank" href="http://www.typecho.org">Typecho</a>&nbsp;|&nbsp;Theme by <a target="blank" href="https://www.ihewro.com/archives/489/">handsome</a>

继续删除以下代码
