博客园自定义自适应主题
分享一下这个博客的美化代码吧,其中包括一套响应式的css,js,雪花和底部小鱼特效。
目录
效果展示
1.宽屏幕
2.小屏幕
找到设置
1. 前往设置
2. 前往博客设置
3. 找到设置
找到如下重要选项
- 博客皮肤(以darkgreentrip为例)
- 页面定制 CSS 代码
- 博客侧边栏公告(请确保开启JS特权)
- 页脚 HTML 代码
(ps如果没有JS特权的话,特效将会消失)
复制代码
复制代码到相应的区域
整合内容大致分布
1.博客侧边栏公告区域:
- 雪花特效
- 头像显示
2.页脚 HTML 代码区域:
- 底部小鱼特效
- 自适应控制
1. 页面定制 CSS 代码部分
代码太长了直接给地址 https://blog-static.cnblogs.com/files/nihilwater/blog.css
2.博客侧边栏公告

一些事项
1.启用“禁用模板默认CSS”
css 部分已经把所有要用到的东西写到了一起,无需再启用模板默认CSS。
2.为什么保存了以后没有反应
在更改完毕以后不会立即生效,需要稍等片刻,可能会比较久,有几次感觉有半个小时才反应过来,在测试的时候建议直接在浏览器里更改源码,测试成功再保存提交。
3.更换背景
在css中找到body和#blogTitle,修改background-image。
