清明时节雨纷纷,但有些地方却下起了大雪,今天我们就用所学的CSS3知识,模拟一下夜晚漫天飘雪的场景吧。
目录
1. 实现思路
2. 部分HTML代码
3. 夜空的背景
4. 雪花的样式
5. 粒子飞升效果
6. HTML完整源代码
7. CSS3完整源代码
8. 最后
- DIV布局的使用
- 整体背景radial-gradient属性的使用
- 夜空rotate属性的使用
- 雪花radial-gradient属性的使用
- 雪花移动动画animation属性的使用
- 雪花移动过程中translate3d属性的使用
因为雪花的元素是相同的,只是移动的起点,移动过程,移动的终点不同,所以HTML元素大致相同,这里我们就不把所有的元素都粘贴过来了,稍后会粘贴出所有源代码,你可以拿到源代码放到自己的网页里,即可看到漫天飘雪的场景啦。
......
夜空为了绚烂一些,肯定不是能是纯黑色,需要做一定的过渡效果,雪花飘落才会更完美,这里用到了background-image: radial-gradient 等CSS属性
body {
background-image: radial-gradient(#021027, #000000);
}
.container {
width: 100%;
height: 100%;
overflow: hidden;
transform: rotate(180deg);
}
雪花虽然HTML元素相同,但表现形式却不同。他有自己的大小,明暗,移动轨迹,等等,越随机,才能越表现的真实而完美
.circle-container .circle {
width: 100%;
height: 100%;
border-radius: 50%;
mix-blend-mode: screen;
background-image: radial-gradient(#99ffff, #99ffff 10%, rgba(153, 255, 255, 0) 56%);
-webkit-animation: fadein-frames 200ms infinite, scale-frames 2s infinite;
animation: fadein-frames 200ms infinite, scale-frames 2s infinite;
}
@-webkit-keyframes scale-frames {
0% {
-webkit-transform: scale3d(0.4, 0.4, 1);
transform: scale3d(0.4, 0.4, 1);
}
50% {
-webkit-transform: scale3d(2.2, 2.2, 1);
transform: scale3d(2.2, 2.2, 1);
}
100% {
-webkit-transform: scale3d(0.4, 0.4, 1);
transform: scale3d(0.4, 0.4, 1);
}
}
可能在第3步,大家看到了 transform: rotate(180deg); 的代码设置,这是做了另外的考虑。满天飞雪的场景,其实如果旋转屏幕,可以做为那种地面上有某种粒子,逐渐向上飞升的效果,也是非常棒的。喜欢的小伙伴可以试一下。
下面把完整源代码放出来,需要的小伙伴可以直接COPY过去,放到自己网页上就可以看到满天飞雪的效果啦
