好的,很高兴为您提供帮助。以下是一个兼容手机端的雪花代码,它可以使雪花自然落下:
HTML:
```
<div class="snowfall"></div>
```
CSS:
```
.snowfall {
position: fixed;
top: 0;
left: 0;
height: 100%;
width: 100%;
z-index: -1;
pointer-events: none;
}
.snowflake {
position: absolute;
top: -10px;
animation: fall 5s infinite linear;
}
@keyframes fall {
from {
transform: translateY(-5px);
}
to {
transform: translateY(100vh);
}
}
```
JS:
```
function snowfall() {
const snowfallDiv = document.querySelector('.snowfall');
const numFlakes = 50;
for (let i = 0; i < numFlakes; i++) {
const snowflake = document.createElement('div');
snowflake.classList.add('snowflake');
snowflake.style.left = `${Math.random() * 100}%`;
snowflake.style.animationDelay = `${Math.random() * 5}s`;
snowflake.innerHTML = '❄️';
snowfallDiv.appendChild(snowflake);
}
}
snowfall();
```
希望这个代码能够帮到您!
