今天更新具体步骤啦!
仅需22步,带领大家,使用css+js绘制超好看的动画!大家可以跟着步骤一步一步编写,也可以直接复制完整代码至编译器,看效果!

一、HTML(index.html)

1. 加入元素

分别加入我们需要的元素,天空,云彩,飞鸟,山川,太阳等,具体看代码中的注释

<!DOCTYPE html><htmllang="en"><head><metacharset="UTF-8"><title>早安、晚安动画</title><linkrel="stylesheet"href="https://cdnjs.cloudflare.com/ajax/libs/meyer-reset/2.0/reset.min.css"><linkrel="stylesheet"href="./style.css"></head><body><divclass="container-wrapper"><h1>Good morning, and in case I don't see ya, good afternoon, good evening, and good night!</h1><pid="subtitle">点点小太阳鸭</p><divclass="container"><divclass="circle-container"><!-- 天空部分 --><divclass="sky"><divclass="sky-night"><divclass="stars"><divclass="shooting-star"></div><divclass="star-group-1"></div><divclass="star-group-2"></div><divclass="star-group-3"></div><divclass="star-group-4"></div></div></div><!-- 云彩 --><divclass="cloud cloud-1"></div><divclass="cloud cloud-2"></div><divclass="cloud cloud-3"></div><divclass="cloud cloud-4"></div><divclass="cloud cloud-5"></div><divclass="cloud cloud-6"></div><divclass="bird bird-1"></div><divclass="bird bird-2"></div><divclass="bird bird-3"></div></div><!-- 山川 --><divclass="mountains"><divclass="mountain-back"><divclass="mountain-back-1"></div><divclass="mountain-back-2"></div></div><divclass="mountain-middle"><divclass="mountain-middle-1"></div><divclass="mountain-middle-2"></div></div><divclass="mountain-top"><divclass="mountain-top-1"></div></div></div><!-- 太阳 --><divclass="sun-container"><divclass="sun"></div></div><!-- 海洋 --><divclass="ocean"><divclass="boat"></div><divclass="ocean-night"><divclass="moon"></div><!-- 山川 --><divclass="mountains mountains-bottom"><divclass="mountain-back"><divclass="mountain-back-1"></div><divclass="mountain-back-2"></div></div><divclass="mountain-middle"><divclass="mountain-middle-1"></div><divclass="mountain-middle-2"></div></div><divclass="mountain-top"><divclass="mountain-top-1"></div></div></div></div></div></div></div></div><!-- partial --><scriptsrc='https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.1/jquery.min.js'></script><scriptsrc="https://cdnjs.cloudflare.com/ajax/libs/prefixfree/1.0.7/prefixfree.min.js"></script><scriptsrc="./index.js"></script></body></html>

请添加图片描述

二、CSS(style.css)

2. 重置浏览器样式

导入

reset.min.css

(已完成),重置浏览器标签的样式表,重新定义标签样式,覆盖浏览器的CSS默认属性,把浏览器提供的默认样式覆盖掉

@importurl("https://fonts.googleapis.com/css?family=Sanchez");*{padding: 0;margin: 0;-webkit-box-sizing: border-box;box-sizing: border-box;}*:before,
*:after{content:"";position: absolute;}

运行效果:
请添加图片描述

3.设置字体样式

html{font-family:"Sanchez", serif;}

运行效果:请添加图片描述

4.将我们的元素居中

.container-wrapper{width: 100%;height: 100%;display: -webkit-box;display: -ms-flexbox;display: flex;-webkit-box-pack: center;-ms-flex-pack: center;justify-content: center;-webkit-box-align: center;-ms-flex-align: center;align-items: center;-webkit-box-orient: vertical;-webkit-box-direction: normal;-ms-flex-direction: column;flex-direction: column;}

运行效果:
请添加图片描述

5.设置背景颜色

html{-webkit-transition: background-color 3s ease;-o-transition: background-color 3s ease;transition: background-color 3s ease;-webkit-transition-delay: 2s;-o-transition-delay: 2s;transition-delay: 2s;background-color: #fff7f4;}

运行效果:
请添加图片描述

6.设置动画显示的位置

子绝父相,这是父元素,设置为相对定位

.container{width: 450px;height: 450px;position: relative;}

7.设置夜晚时的背景色

我们将会在js中使用它

.container-night{background-color: #e4ecff;}

8.将动画显示的区域设置为圆型

根据最终效果,我们将动画显示的区域设置为原型

.circle-container{width: 450px;height: 450px;-webkit-clip-path:circle(50% at 50% 50%);clip-path:circle(50% at 50% 50%);position: absolute;overflow: hidden;z-index: 100;}

9.绘制白天时天空的样子

.sky{position: absolute;width: 100%;height: 55%;top: 0;background:-webkit-gradient(
            linear,
            left top,
            left bottom,
            from(#feb8b0),
            to(#fef9db));background:-webkit-linear-gradient(#feb8b0, #fef9db);background:-o-linear-gradient(#feb8b0, #fef9db);background:linear-gradient(#feb8b0, #fef9db);z-index: 1;overflow: hidden;}

运行效果:请添加图片描述

10.绘制夜晚时天空的样子

绘制夜晚时天空的样子,我们使用opacity属性,将其设置为不可见,在js中使用toggleClass方法将该属性切换为1,使其可见,后头很多动画都是这么实现的。运行效果的图中将该属性设置为了1,方便大家先看到效果

.sky-night{position: absolute;width: 100%;height: 100%;background:-webkit-gradient(
            linear,
            left top,
            left bottom,
            from(#4c3f6d),
            color-stop(#6c62bb),
            to(#93b1ed));background:-webkit-linear-gradient(#4c3f6d, #6c62bb, #93b1ed);background:-o-linear-gradient(#4c3f6d, #6c62bb, #93b1ed);background:linear-gradient(#4c3f6d, #6c62bb, #93b1ed);opacity: 0;-webkit-transition: opacity 3s;-o-transition: opacity 3s;transition: opacity 3s;-webkit-transition-delay: 2s;-o-transition-delay: 2s;transition-delay: 2s;}/*用于切换opacity属性*/.sky-night-fade{opacity: 1;}

运行效果:

11.创建昼夜交替动画

@-webkit-keyframes sky-night{0%{background:-webkit-gradient(
                linear,
                left top,
                left bottom,
                from(#feb8b0),
                to(#fef9db));background:-webkit-linear-gradient(#feb8b0, #fef9db);background:linear-gradient(#feb8b0, #fef9db);}100%{background:-webkit-gradient(
                linear,
                left top,
                left bottom,
                from(#4c3f6d),
                to(#96b5ee));background:-webkit-linear-gradient(#4c3f6d, #96b5ee);background:linear-gradient(#4c3f6d, #96b5ee);}}@keyframes sky-night{0%{background:-webkit-gradient(
                linear,
                left top,
                left bottom,
                from(#feb8b0),
                to(#fef9db));background:-webkit-linear-gradient(#feb8b0, #fef9db);background:-o-linear-gradient(#feb8b0, #fef9db);background:linear-gradient(#feb8b0, #fef9db);}100%{background:-webkit-gradient(
                linear,
                left top,
                left bottom,
                from(#4c3f6d),
                to(#96b5ee));background:-webkit-linear-gradient(#4c3f6d, #96b5ee);background:-o-linear-gradient(#4c3f6d, #96b5ee);background:linear-gradient(#4c3f6d, #96b5ee);}}

            linear,
            left top,
            left bottom,
            from(#fefefe),
            to(#fffbe8));background:-webkit-linear-gradient(#fefefe, #fffbe8);background:-o-linear-gradient(#fefefe, #fffbe8);background:linear-gradient(#fefefe, #fffbe8);cursor: pointer;z-index: 10;}

三、JS(index.js)

22. 设置元素间属性转换

js部分主要是元素的变换,日夜交替时,显示或者隐藏某个元素,较为简单

$(function(){$('.sun').click(function (e){
        e.stopPropagation();$("html").toggleClass('container-night');$(".sky-night").toggleClass('sky-night-fade');$("p, h1").toggleClass('text-color');$(".ocean-night").toggleClass('ocean-night-fade');$(".moon").toggleClass('moon-fade');$(".ocean").toggleClass('animation-stop');$(".bird").toggleClass('birds-fly');$(".boat").toggleClass('boat-sail');$(".mountain-top, .mountain-top >*").toggleClass('mountain-top-night');$(".mountain-middle, .mountain-middle >*").toggleClass('mountain-middle-night');$(".mountain-back, .mountain-back >*").toggleClass('mountain-back-night');$(".cloud").delay(2500).fadeToggle(2500);$(".stars").toggleClass('stars-fade');$(".shooting-star").toggleClass('shooting');

        var angle =($('.sun-container').data('angle') + 360)|| 360;$('.sun-container').css({'transform':'rotate(' + angle + 'deg)'});$('.sun-container').data('angle', angle);});});

至此,我们的纯代码绘制动画就完成啦!
