马上就要过年了，看着我这毫无生气的博客，感觉有点亏待它。博客过年，马上安排！
本篇部分知识基于上两篇博客博客园主题修改分享和博客园主题修改分享 - 脚本篇。

先上效果图

1. 设置全局css变量

主要是通过css3的变量设置，统一博客界面的颜色。

:root {
    --bg: #f5f7f9;
    /* --main: #169fe6;
    --hover: #45bcf9; */
    --main: #ff0000;
    --hover: #fb5050;
}

修改原来的色调为红色，过完年后可复原。
修改其他主体颜色，统一设置为主题色。

/*首页修改*/
#navigator {
    background-color: var(--main);
    border: none;
}
#profile_block a {
    color: var(--main);
}
/* 分页 */
#nav_next_page a {
    background-color: var(--hover);
}
.pager {
    color: var(--main);
}

如上，修改的地方为博客园设置的页面定制CSS代码。

下面附上所有代码：

提示：以下代码基于主题CondingLife修改，非此主题者，请自行修改代码内对应颜色即可。

:root {
    --bg: #f5f7f9;

如果您之前对博客侧边栏公告也有修改的话，也需要修改颜色为主题色，如下示例，请自行修改

2. 增加欢度春节的灯笼

纯CSS样式，需要在页首HTML代码里新增代码。
代码如下：

<style>
  :root {
    --lantern-bg: rgba(255, 0, 0, .8);
    --lantern-text-color: #ffc14e;
    --lantern-line-color: #ffa500;
  }
  .lantern-box {
    position: fixed;
    top: -10px;
    right: -20px;
    max-width: 200px;
    z-index: 1999;
  }
  .lantern-box1 {
    top: -20px;
    right: 60px;
  }
  .lantern-box2 {
    top: 0px;
    right: 140px;
  }
  .lantern-box3 {
    top: -10px;
    right: 220px;
  }

  .lantern-box1 .lantern,
  .lantern-box3 .lantern{

  }

  .lantern {

灯笼的位置可自行修改，调整.lantern-box1-4的top和right属性即可。如果你想让灯笼置左,删除right属性，设置left即可。

让博客和你一起过年，祝大家新年快乐！
