先上一张效果图:
这种动态的背景特效,制作起来其实非常简单。
使用了particles.js
particles.js可以从github网站下载到最新的源码,网址是 https://github.com/VincentGarreau/particles.js/
使用方法非常简单
第一步,在html中引入脚本文件 particles.min.js,这个文件在下载的压缩包里可以找到
<script src="particles.min.js"></script>
第二步,在html中放入一个div容器,设置id为particles-js。这个一般放在所有网页元素的最后面就可以。
<div id="particles-js"></div>
<style type="text/css">
#particles-js {
position: absolute;
top:0;
width:100%;
}
</style>
第三步,设置窗口样式
<style type="text/css">
#particles-js {
z-index: -1;
position: absolute;
top: 0;
width: 100%;
background: #aaa;
} </style>
第四步,脚本生成粒子效果,可以单独放在一个js文件里,也可以放在<script>标签里。无论如何,这段脚本要出现在div容器之后。
particlesJS("particles-js", { "particles": { "number": { "value": 380, "density": { "enable": true, "value_area": 800 } }, "color": { "value": "#ffffff" }, "shape": { "type": "circle", "stroke": { "width": 0, "color": "#000000" }, "polygon": { "nb_sides": 5 }, "image": { "src": "img/github.svg", "width": 100, "height": 100 } }, "opacity": { "value": 0.5, "random": false, "anim": { "enable": false, "speed": 1, "opacity_min": 0.1, "sync": false } }, "size": { "value": 3, "random": true, "anim": { "enable": false, "speed": 40, "size_min": 0.1, "sync": false } }, "line_linked": { "enable": true, "distance": 150, "color": "#ffffff", "opacity": 0.4, "width": 1 }, "move": { "enable": true, "speed": 6, "direction": "none", "random": false, "straight": false, "out_mode": "out", "bounce": false, "attract": { "enable": false, "rotateX": 600, "rotateY": 1200 } } }, "interactivity": { "detect_on": "canvas", "events": { "onhover": { "enable": true, "mode": "grab" }, "onclick": { "enable": true, "mode": "push" }, "resize": true }, "modes": { "grab": { "distance": 140, "line_linked": { "opacity": 1 } }, "bubble": { "distance": 400, "size": 40, "duration": 2, "opacity": 8, "speed": 3 }, "repulse": { "distance": 200, "duration": 0.4 }, "push": { "particles_nb": 4 }, "remove": { "particles_nb": 2 } } }, "retina_detect": true });
完工。
