今天我们来写表白爱心代码

首先HTML里body只要写两行代码就可以了，后面都是js代码了

我们的样式css代码如下：

首先我们先定义一个Settings

1. 请求动画帧填充

RequestAnimationFrame polyfill by Erik M?ller

2.点类

Point class

3.粒子类

Particle class

4.ParticlePool 池类

ParticlePool class

5.创建和填充

create and populate particle pool

6.处理循环队列

handle circular queue

7.更新活动粒子

update active particles

8.移除非活性粒子

remove inactive particles

9.绘制有源粒子

draw active particles

10.整合

Putting it all together

11.进行样式表达

get point on heart with -PI <= t <= PI

12.使用虚拟画布创建粒子图像

creating the particle image using a dummy canvas

13.用来创建路径的辅助器功能

helper function to create the path

14.创建路径

create the path

15.创建填充

15.创建图像

16.做出成果

17.创建新的粒子

18.更新和绘制粒子

update and draw particles

19.重新处理画布大小

20. 延迟渲染引导

delay rendering bootstrap

21.全部代码

好了，这就是全部爱心代码了

今天是三八女神节，无论是小妹妹还是大姐姐，我都想对我的同性说：生活处处充满美好，无论身处什么逆境，都应该往前看，一切都会过去的，我们女性大部分都会因为感情，学业，家庭的等困扰所影响，我一直觉得感情应该以佛系的态度看待，学业，努力向上我觉得就很幸福，自己想要的自己去努力争取，不去依附她人，做自己的女王，你就是这个世界最闪闪发光的人！！！
