前言：

网站底部太单调，增加点底部菜单内容。

插入CSS代码：

/*网站底部按钮美化_xjvae博客[www.xjvae.com]*/
:root{--theme-color:#f04494;--focus-shadow-color:rgba(240,68,148,.4);--mian-max-width:1200px;}.github-badge {
    display: inline-block;
    border-radius: 4px;
    text-shadow: none;
    font-size: 12px;
    color: #fff;
    line-height: 15px;
    margin-bottom: 5px;
}
.badge-subject {
    display: inline-block;
    background-color: #4d4d4d;
    padding: 4px 4px 4px 6px;
    border-top-left-radius: 4px;
    border-bottom-left-radius: 4px;
}
.github-badge .bg-blue {
    background-color: #007ec6;
}
.github-badge .bg-brightgreen {
    background-color: #4dc820;
}
.github-badge .bg-blueviolet {
    background-color: #8833d7;
}
.github-badge .badge-value {
    display: inline-block;
    padding: 4px 6px 4px 4px;
    border-top-right-radius: 4px;
    border-bottom-right-radius: 4px;
}
.github-badge .bg-orange {
    background-color: orange;
}
/*网站底部按钮美化_xjvae博客[www.xjvae.com]*/

 底部小工具插入HTML代码：

<!--网站底部按钮美化HTML_xjvae博客[www.xjvae.com]-->
<div class="github-badge">

  <span class="badge-subject bg-blue">
     <a style="color:#fff" href="https://www.xjvae.com" target="_blank">友链申请</a>
  </span>-
  <span class="badge-subject bg-brightgreen">
     <a style="color:#fff" href="https://www.xjvae.com" target="_blank">网站地图</a>
  </span>-
  <span class="badge-subject bg-green">
     <a style="color:#fff" href="https://www.xjvae.com" target="_blank">本站主题</a>
  </span>-
    <span class="badge-value bg-blueviolet">
     <a style="color:#fff" href="https://www.xjvae.com" target="_blank">免责申明</a>
  </span>

</div>
