前言
时光荏苒,白驹过隙。2022这一年又在忙碌中度过了,过去的一年,我们同努力,我们共欢笑,每一次成功都蕴藏着我们辛勤的劳动。
新的一年即将来到,我们不能停滞不前,一味只是骄傲。愿大家与时俱进,拼搏不懈,共创新的辉煌!
借着新年到来的喜庆,给大家分享一个新年烟花的前端代码,快拿着代码展示给你的朋友们看吧!!
效果展示
文末有完整代码,只需要下载压缩包,解压运行即可。接下来我们一起来看完整教程吧。
烟花的样式既可以是随机的,也可以自定义,风格样式齐全。搭配烟花燃放时的音乐,新年的氛围在此刻达到了顶峰!快和你的小伙伴一起分享这份快乐吧。
使用方法
代码已经打包,想下载学习的小伙伴:免费下载
第一步:首先,下载压缩包,解压后我们就可以看到下面这样一个文件夹。
第二步:打开文件夹,此时我们可以看到文件夹里有三个文件。
不要着急,我们先来看看文件夹里都有什么吧,首先是 HTML 文件,负责这个程序的主要结构,其次是样式表文件 CSS ,还有一个就是代码的逻辑部分JavaScrirt。
第三步:点击第一个文件 index.html ,双击运行,此时我们就可以拿着程序展示给小伙伴啦,别忘了打开声音特效哦。
对于小白来说,是不是比桌面新建一个文本文档的方法友好多了呢?其实我们就是为了新年这场美好的氛围,快和你的朋友来一场线上烟花吧!
源码学习
当然,对于学习前端的小伙伴,我们不光要看一场绚丽的烟花,还要学习代码为什么要这么写喽,接下来我们一起来看一看吧!
HTML代码
HTML 就像骨头一样,撑起了整个页面的大致框架,比如左边需要一个输入框,右边需要一个按钮之类的,都可以用HTML来实现。

CSS代码
HTML实现出来的样式是比较单调的,而CSS实现了美化的效果。
* { position: relative; box-sizing: border-box; } html, body { height: 100%; } html { background-color: #000; } body { overflow: hidden; color: rgba(255, 255, 255, 0.5); font-family: "Russo One", arial, sans-serif; line-height: 1.25; letter-spacing: 0.06em; } .hide { opacity: 0; visibility: hidden; } .remove { display: none !important; } .blur { filter: blur(12px); } .container { height: 100%; display: flex; justify-content: center; align-items: center; } .loading-init { width: 100%; align-self: center; text-align: center; text-transform: uppercase; } .loading-init__header { font-size: 2.2em; } .loading-init__status { margin-top: 1em; font-size: 0.8em; opacity: 0.75; } .stage-container { overflow: hidden; box-sizing: initial; border: 1px solid #222; margin: -1px; }
JavaScript 代码实现了与用户的交互逻辑,由于代码比较长,就不再展示啦。
