一个有意思的小脚本
见博客：https://www.luogu.com.cn/blog/liutianyou/Luogu-Extra
很多人貌似很喜欢我的脚本，所以我把几个大佬的脚本整合了一下发出来，私信提示和换背景完全是我自己开发的。
下文来自上面的博客。
由于使用氩洛谷、exlg之类的插件过于麻烦，本人开发出来一个增强洛谷功能油猴脚本。
使用脚本之前，你需要安装“Tampermonkey”插件，你在你的浏览器扩展商店中可以找到。
下面是脚本内容，你需要对它进行微调，然后就可以用了。

你需要进行的修改如下：
-
将
var background =之后的URL改为你的背景图片，可以放任意个，会随机选择图片. -
将洛谷改为默认主题.
这个脚本的功能：
-
修改背景图片，透明化内容
-
实时接收私信，并在右上角以提示方式给出.
-
主页 -> 练习中的题目带颜色.
-
按照难度随机跳转题目
修复的Bug：
-
更改题目颜色功能干扰验证码运行（2022年7月7日修复）
-
透明度适用于博客编辑框（2022年7月7日修复）
-
拒绝div不存在而错误终止脚本的情况（2022年7月7日修复）
功能会持续更新，但目前不打算放到Tampermonkey的官网上.请认准这篇博客，并检查你的更新.
这份代码是结合了其他大佬的代码而成的，具体可见代码.
效果图：
PS：这个私信提示真的好用，刚刚收私信的时候右上角就来提示了……
