js+css实现磨砂效果制作

一直很喜欢新海诚的作品，前几天又温故了一遍《天气之子》，还是会被阳莱和帆高的故事感动。

效果图：

 

 

 

 

废话少说，直接上代码

html部分

        

            <我的前端小屋 />
        
        

            
天气之子 {
            
现在开始天晴了
            
相比于蓝天，我更想选择阳莱

            
 一起勇敢地爱下去
            
}
        
        遇见你

电影中十分打动我的台词

能遇见你，真的是太好了
天气因你逆转，世界因你天晴
无论你在哪里，我一定拼劲全力去见你
我只是想再一次的见到她啊
