更快的方法分散多个图像项目html

Question

我对动画很陌生，我目前正在努力实现以下的目标:然而，因为我想让这些星星在你盘旋的时候摆动，我发现我需要手动插入每一颗星星，而不仅仅是插入这张图片。是否有更快/更有效的方法来解决这个问题？我应该为此编写一个插入js函数吗？谢谢!

Answer 1

您可以使用2张图片与同一位置的恒星。第一张图片是这一张，第二张图片是明亮的恒星，然后在短时间内替换它们。

​

setInterval(function(){
	$('img').prop('src', 'https://preview.ibb.co/kfbsWk/kpme4_brighter.png');
}, 200);

setTimeout(function(){
	setInterval(function(){
		$('img').prop('src', 'https://preview.ibb.co/fSHzBk/kpme4.png');
	}, 200);
	}, 100
);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a href="https://ibb.co/evgRrk"><img src="https://preview.ibb.co/fSHzBk/kpme4.png" alt="kpme4" border="0"></a><br /><a target='_blank' href='https://vi.imgbb.com/'>image host</a><br />

Answer 2

你可能需要Particles.js

用于创建粒子的轻量级JavaScript库。

用法很简单。

1. 从CDN或本地加载库。我用过 <script src="https://cdnjs.cloudflare.com/ajax/libs/particles.js/2.0.0/particles.min.js"></script>
2. 用id="particles-js"为粒子创建容器
3. 它的风格如下： #particles-js { width: 100vw; height: 100vh; overflow: hidden; }
4. 转到官方网页，设置您想要的任何设置
5. 导出设置为json
6. 在文档中的<script>标记中添加json内容。

如果喜欢一些非交互式的东西，因为这样可能有更好的整体性能，那么可以实现这样一个简单得多的版本：

​

* {
  margin: 0;
  padding: 0;
}

.stars,
.twinkle {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  display: block;
  z-index: -10;
}

.stars {
  background: #000 url(https://i.stack.imgur.com/SyeSl.png) repeat top center;
  z-index: -1;
}

.twinkle {
  background: transparent url(https://i.stack.imgur.com/q9Sz6.png) repeat top center;
  z-index: -1;
  animation: stars 1000s linear infinite;
}

@keyframes stars {
  from {
    background-position: 0 0;
  }
  to {
    background-position: -10000px 5000px;
  }
}

<div class="stars"></div>
<div class="twinkle"></div>
