目录

前言

又是一年中秋至,漂泊异乡的你是否又会看着月亮思念故乡的亲人,又或是想起了天涯海角的友人!这篇文章我将以程序员的方式用代码写出“海上生明月”中秋节网页特效,在此献给广大网友,祝你们中秋快乐!

海上生明月 天涯共此时

因为这个代码用到了这两句诗,特此提出来供各位盆友欣赏一下,作为码农的我们,长期处于电脑屏幕前看着枯燥的代码,或由于工作繁忙而导致的压力,因此很少有时间去陶冶情操,放松身心!因此在看代码前先请各位欣赏诗句,就如同我们现在回看初高中的语文课本,又会有不一样的感触,后悔当时没能好好体悟!毕竟谁的心里不藏着一个文艺小青年呢!

望月怀远作者:张九龄(唐代)海上生明月,天涯共此时。情人怨遥夜,竟夕起相思。灭烛怜光满,披衣觉露滋。不堪盈手赠,还寝梦佳期。

在这里插入图片描述
《望月怀远》是作者在离乡时,望月而思念远方亲人及妻子而写的,“海上生明月 天涯共此时”,意思是指辽阔无边的大海上升起一轮明月,诗人想起了远在天涯海角的友人,此时此刻他也和我一样望着同一轮明月。诗是通过主人公望月时思潮起伏的描写,来表达诗人对远方之人殷切怀念的情思。
好了,接下来我们步入正题!

代码主体思路

  1. 首先,我们要创建一个定时器,使得月亮 div id=“moon” 不断上升!
  2. 当月亮上升到距离顶部120像素时,清除定时器,月亮上升停止!
  3. 当月亮停止之后,让里面的诗句逐字(定时器实现)显示,让嫦娥图片显示!
  4. 一系列 div class=“stars” 是创建夜空中的星星,并加上css动画让其动起来!
  5. div id=“water” 是底部涌动的海水
