一，前言

又是一年中秋节,明月千里寄相思秋风起,日渐凉,时光似水般轻轻从指尖划过,转眼又是一年一度的中秋节。这篇文章将以程序员的方式呈现中秋佳节，希望大家喜欢，祝你们中秋快乐！

《望月怀远》是唐代诗人张九龄的作品。此诗是望月怀思的名篇。

赏析

《望月怀远》是一首月夜怀念远人的诗，是作者在离乡时，望月而思念远方亲人而写的。起句“海上生明月，天涯共此时”，茫茫的海上升起一轮明月，此时你我都在天涯共相望。有情之人都怨恨月夜漫长，整夜里不眠而把亲人怀想。熄灭蜡烛怜爱这满屋月光，我披衣徘徊深感夜露寒凉。不能把美好的月色捧给你，只望能够与你相见在梦乡。

三，思路

首先，我们要创建一个定时器，使得月亮 div id=“moon” 不断上升！
当月亮上升到距离顶部,同时显示starUnder130像素时，清除定时器，月亮上升停止！
当月亮停止之后，让里面的诗句逐字（定时器实现）显示，通过设置的动画让嫦娥图片显示！
class="stars"是创建夜空中的星星，并加上css动画让其动起来！
div id=“water” 是底部倒影
