网站点击彩色效果[整站笔记]-紫禁源码资源站

Death comes to all, but great achievements raise a monument which shall endure until the sun grows old.

死亡无人能免，但非凡的成就会树起一座纪念碑，它将一直立到太阳冷却之时

这一个很简单的网站点击彩色的效果，采用js来实现的，现在就分享给大家吧！教程的话就简单说一下吧。首先创建JS文件，复制下面的代码，粘贴到文件中，然后用script标签调用：代码调用如：<script src=”/cdn/js/dianji.js”></script>，就可以啦！Worderss主题一般都在后台主题设置里的自定义JS代码里添加，其他大同小异。
