前言：这些小项目全都是自创的。
如果需要应用，或则转发的话请与
博主联系，感谢你们的理解，
1.自定义播放器
在页面中放置26个div，每个div中写一个字
母。html结构中引入8个音频结构。给每个
div绑定点击键盘事件。根据键盘的每个
keyCode的不同来动态绑定对应的音频文件。
当按下对应的键盘字母，增添css样式，
音频播放。放开时，存储点击的事件，
将对应的音频存储在一个数组中。
点击按钮，循环播放存储的音频数组

2.图片自动消失
一张图片，在其右上角放置一个div
，分别得到那个元素，在div中插入数字
开启一个定时器，每隔一段时间减一。
直到为0.图片消失
<style>
.ad{
width:400px;
height:400px;
background-image: url(img/1.jpg);
position:relative;
margin:200px auto;
}
#sj{
display:block;
width:40px;
height:40px;
line-height:30px;
border-radius:50%;
border:1px solid red;
position:absolute;
top:20px;
right:20px;
text-decoration: none;
text-align: center;
line-height: 40px;
font-size: 20px;
}
</style>
</head>
<body>
<div id="gg" class="ad">
<a href="" > <span id="sj">5</span></a>
</div>
<script>
var gg=document.getElementById("gg");
var sj=document.getElementById("sj")
var time=setInterval(function(){
sj.innerHTML-=1;
if(sj.innerHTML==0){
gg.style.display="none";
clearInterval(time);
}
},1000);
</script>
</body>yy3.小轮播图
放置三张图片，移动到那个图片，
改变他的偏移量。
*{
padding:0;
margin:0;
}
body,html{
width:100%;
overflow:hidden;
}
#wrap1{
width:100%;
position:absolute;
bottom:0;
left:0;
text-align: center;
}
#wrap1>img{
width:64px;
}
</style>
</head>
<body>
<div id="wrap1">
<img src="img/1.png" />
<img src="img/2.png" />
<img src="img/3.png" />
<img src="img/4.png" />
<img src="img/5.png" />
</div>
<script type="text/javascript">
window.onload=function(){
var r=320
var imgNodes=document.querySelectorAll("#wrap1>img")
document.onmousemove=function(ev){
ev=ev||event
for(var i=0;i<imgNodes.length;i++){
var a= imgNodes[i].getBoundingClientRect().top+imgNodes[i].offsetHeight/2-ev.clientY
var b= imgNodes[i].getBoundingClientRect().right+ imgNodes[i].offsetWidth/2-ev.clientX
var c=Math.sqrt(a*a+b*b)
if(c>=r){
c=r
}
imgNodes[i].style.width=128-c*0.2+'px'
}
}
}
</script>4.旋转音乐盒
旋转音乐盒
放置六张图片，将他们绝对定位。
根据所学css来对每一张图片进行定位
然后就是当点击哪一个图片时，播放
对应的音频音乐。
css：
*{
padding:0;
margin:0;
}
.cube{
width:200px;
height:200px;
position: relative;
margin:200px auto;
//使效果呈现3d效果
transform-style: preserve-3d;
animation: rotate 30s infinite linear;
}
@keyframes rotate{
from{
transform:rotateX(0deg) rotateY(0deg);
}
to{
transform: rotateX(360deg) rotateY(360deg);
}
}
html{
//屏幕与我们的视距
perspective: 10000px;
}
.cube>div{
width:200px;
height:200px;
position:absolute;
opacity: 0.7;
}
img{
width:200px;
height:200px;
}
.box1{
transform: rotateX(90deg) translateZ(100px);
}
.box2{
transform: rotateX(-90deg) translateZ(100px);
}
.box3{
transform: rotateY(0deg) translateZ(100px);
}
.box4{
transform: rotateY(180deg) translateZ(100px);
}
.box5 {
transform: rotateY(90deg) translateZ(100px);
}
.box6 {
transform: rotateY(-90deg) translateZ(100px);
}
.change{
transform: translateZ(50px);
}
</style>html：

for(let i=0;i<divs.length;i++){
for(let j=0;j<audios.length;j++){
if(divs[i].dataset.key===audios[j].dataset.key){
divs[i].onclick=function(){
audios[j].play()
}
}
}
