本文介绍如何利用HTML、CSS和JavaScript创建新年数字烟花效果,提供详细教程和代码示例,帮助读者了解前端开发技术在新年庆祝活动中的应用。
烟花绚丽多彩的绽放,一直以来都是新年庆典中不可或缺的元素。
如何利用技术的魔力,创造出炫目绝伦的数字烟花,成为了技术爱好者们所追寻的目标。在这篇文章中,带领大家探索如何借助代码的魔力,打造出令人惊叹的数字烟花效果,为新年之夜增添一抹绚烂的色彩。
烟花样式可以自定义选择,背景音乐选择十分真实的仿烟花声。当你把代码打包发给朋友打开时,新年的氛围在此刻达到了顶峰。也许你在这一年里背井离乡忙于工作,学习,也许你在这一年里过得风生水起,做着喜欢的工作,又或是这一年里,你过的不尽人意,新年到来之时,忘记所有烦恼,在家多陪陪父母,出门和朋友聚会,2024 年我们重头再来!
无论是你想自己研究代码,还是你是小白想发给朋友欣赏,都十分推荐。一共三个文件,分别是:
这三个部分便是我们常说的前端三剑客,是前端的基础内容,构成了前端技术栈。其中,HTML负责结构部分,他就像是骨架一样,CSS 又叫层叠样式表,负责页面的美化,还有负责交互逻辑的 JavaScript 。感兴趣的朋友可以看看这套html基础教程文章:HTML入门教程(非常详细)
对于小白来说,网上有很多的教程,可以说是眼花缭乱。这样的方式是不是方便很多呢?不用你新建一个记事本文件。哈哈,重点还是能在代码里学到东西哦,烟花只是为了新年的氛围!!
由于文章的篇幅原因,代码只展示一部分示例。HTML 撑起了整个页面的大致框架,不如你想给页面加上一个按钮,一个输入框等等。他是页面的骨架,负责页面的结构部分。

当然,只使用 HTML 的页面是十分单调的,我们还需要对页面进行美化,此时需要加入 CSS 代码。
.help-modal__overlay {
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
opacity: 0;
transition-property: opacity;
transition-timing-function: ease-in;
transition-duration: 0.25s;
}
.help-modal__dialog {
display: flex;
flex-direction: column;
align-items: center;
max-width: 400px;
max-height: calc(100vh - 100px);
margin: 10px;
padding: 20px;

JavaScript 处理代码的交互逻辑,是十分重要的一部分,也是比较难的一部分。
function toggleSound(toggle) {
if (typeof toggle === 'boolean') {
store.setState({ soundEnabled: toggle });
} else {
store.setState({ soundEnabled: !store.state.soundEnabled });
}
}
function toggleMenu(toggle) {
if (typeof toggle === 'boolean') {
store.setState({ menuOpen: toggle });
} else {
store.setState({ menuOpen: !store.state.menuOpen });
}
}
function updateConfig(nextConfig) {
nextConfig = nextConfig || getConfigFromDOM();
store.setState({
config: Object.assign({}, store.state.config, nextConfig)
});
configDidUpdate();
}
// Map config to various properties & apply side effects
function configDidUpdate() {
const config = store.state.config;
quality = qualitySelector();
isLowQuality = quality === QUALITY_LOW;
isNormalQuality = quality === QUALITY_NORMAL;
isHighQuality = quality === QUALITY_HIGH;
if (skyLightingSelector() === SKY_LIGHT_NONE) {
appNodes.canvasContainer.style.backgroundColor = '#000';
}
Spark.drawWidth = quality === QUALITY_HIGH ? 0.75 : 1;
}
