实现波浪背景动态无限次循环播放（连续性）

图片：左边的图像与右边的图像是完全重合（高度一致）
HTML页面：使用background-image属性引入波浪图片
- 将背景图像显示成水平方向两个完全重复的效果
  - 将引入图片的div元素的宽度设置为父级容器的200%
  - 通过background-size属性设置为背景图像水平方向的值为50%
- 设置动画执行的关键帧时，将100%时的关键帧设置为50%.

小米轮播图（左右按钮）

实现思路

需要五组input+label标签（且input标签的type为radio） /* 第一个需带有checked，因为默认情况下选择的是第一个，也就是默认情况下第一个被选中 */ <input type="radio" name="slide" id="slide1" checked /> <input type="radio" name="slide" id="slide2" /> <input type="radio" name="slide" id="slide3" /> <input type="radio" name="slide" id="slide4" /> <input type="radio" name="slide" id="slide5" /> <label for="slide1" class="slide slide1"></label> <label for="slide2" class="slide slide2"></label> <label for="slide3" class="slide slide3"></label> <label for="slide4" class="slide slide4"></label> <label for="slide5" class="slide slide5"></label> label标签的for属性与input标签的id属性相对应。也就是说当点击第一个label标签时，第一个input被选中,点击第二个label标签时，第二个input被选中……
在CSS上，默认图片透明度均为0，层级（z-index）默认也为0。
利用伪类选择器（:checked）来判断哪张图片应该被显示简单来说就是当第一个input加入checked属性时(被选中时)，那么他的层级(z-index)与透明度则变为1。其他也是同理，因为默认的层级与透明度都是0，所以当选择另外input时刚才那个就会回到默认状态
左右按钮的实现首先应该明确的是第几张图片出现时左右按钮应该指向哪一张图片。例如当显示第一张图片时左按钮应去向第五章，右按钮应去向第二张。其次就是这些按钮应该随着不同图片的出现而变换，类似于一个按钮绑定一个图片。图片左按钮右按钮第一张图片第五张第二张第二章图片第一张第三张第三章图片第二张第四张第四章图片第三张第五张第五章图片第四张第一张
最后只需要用input是否被checked就可以判断哪一个label标签应该显示。

轮播图的导航栏

导航栏基于上一个可以左右滑动的轮播图实现。实现方法很简单。

由于已经实现了可以切换图片的label标签，因此复制一个一模一样的即可。 <div class="nav"> <label for="slide1"></label> <label for="slide2"></label> <label for="slide3"></label> <label for="slide4"></label> <label for="slide5"></label> </div>
接下来需要做的就是继续将每一张图片与刚加入的label标签绑定 #slide1:checked~.nav label:nth-child(1), #slide2:checked~.nav label:nth-child(2), #slide3:checked~.nav label:nth-child(3), #slide4:checked~.nav label:nth-child(4), #slide5:checked~.nav label:nth-child(5) { border-color: rgba(0, 0, 0, .4); background: hsla(0, 0%, 100%, 1); }
这样基本上就可以了，至于显示位置及样式根据自己调整即可。

百叶窗效果

在实现了上述轮播图后实现百叶窗效果是需要改造的。

首先是HTML结构，图片列表使用的是img标签，百叶窗实际上是将图片分割成不同的小块然后逐个切换。所以需要将HTML结构改造为一个div（作为每个小块的容器）嵌套若干个（这里用四个举例）div（作为图片展示） <div class="imgList"> <div class="img"> <div class="frag"></div> <div class="frag"></div> <div class="frag"></div> <div class="frag"></div> </div> <div class="img"> <div class="frag"></div> <div class="frag"></div> <div class="frag"></div> <div class="frag"></div> </div> <div class="img"> <div class="frag"></div> <div class="frag"></div> <div class="frag"></div> <div class="frag"></div> </div> <div class="img"> <div class="frag"></div> <div class="frag"></div> <div class="frag"></div> <div class="frag"></div> </div> <div class="img"> <div class="frag"></div> <div class="frag"></div> <div class="frag"></div> <div class="frag"></div> </div> </div> 上述结构中，img作为每张图片的容器，frag是实际上展示图片的容器。也就是每个frag显示图片的四分之一（随窗口数而定）
对于img与frag两个class的样式需要调整为 .container .imgList .img { height: 100%; width: 100%; height: auto; position: absolute; left: 0; top: 0; } .container .imgList .img .frag { float: left; height: 460px; width: 25%; background-size: 1226px 460px; opacity: 0; z-index: 0; } frag的宽度为容器的25%也就是四分之一，高度也是容器的高度。由于这个效果是基于每个小块的不同切换效果实现的，那么自然需要将背景图像的大小调整好也就是background-size属性。
设置每块容器(img)里每个小块(frag)显示的图片 .container .imgList .img:nth-child(1) .frag { background-image: url(https://ae01.alicdn.com/kf/U1a6b653720d845c682f97d2fcf75c22f6.png); } .container .imgList .img:nth-child(2) .frag { background-image: url(https://cdn.cnbj1.fds.api.mi-img.com/mi-mall/6bd4174b8c5aad67a64864a5716ad152.jpg); } .container .imgList .img:nth-child(3) .frag { background-image: url(https://cdn.cnbj1.fds.api.mi-img.com/mi-mall/e909ef0e50960f61a730380013bc960a.jpg); } .container .imgList .img:nth-child(4) .frag { background-image: url(https://cdn.cnbj1.fds.api.mi-img.com/mi-mall/755aca9487082e7698e16f17cfb70839.jpg); } .container .imgList .img:nth-child(5) .frag { background-image: url(https://cdn.cnbj1.fds.api.mi-img.com/mi-mall/e5b37cdb85b3b93b5938cc508a10c906.jpg); }
调整四小块中每一块显示的区域。这一步很简单，如果不修改每一块的位置，那么四张图显示的都是一样的。而我们需要的是四小块拼成一个完整的。并且每一个都是有一个延迟的，所以同样需要为每一个小块设置延迟时间(transition-delay)。 .container .imgList .img .frag:nth-child(2) { background-position: -306.5px 0; transition-delay: .2s; } .container .imgList .img .frag:nth-child(3) { background-position: -613px 0; transition-delay: .3s; } .container .imgList .img .frag:nth-child(4) { background-position: -919.5px 0; transition-delay: .4s; } .container .imgList .img .frag:nth-child(5) { background-position: -1226px 0; transition-delay: .5s; }
调整当按钮(label标签)点下去时改变的元素。 #slide1:checked~.imgList .img:nth-child(1) .frag, #slide2:checked~.imgList .img:nth-child(2) .frag, #slide3:checked~.imgList .img:nth-child(3) .frag, #slide4:checked~.imgList .img:nth-child(4) .frag, #slide5:checked~.imgList .img:nth-child(5) .frag { opacity: 1; z-index: 1; }
此时页面已经可以有基本效果了。接下来需要做的只是美化。 #slide1:checked~.imgList .img:nth-child(1) .frag, #slide2:checked~.imgList .img:nth-child(2) .frag, #slide3:checked~.imgList .img:nth-child(3) .frag, #slide4:checked~.imgList .img:nth-child(4) .frag, #slide5:checked~.imgList .img:nth-child(5) .frag { opacity: 1; z-index: 1; transform: rotateY(90deg) translateZ(180deg) scale(1.5); filter: saturate(1) blur(0px) brightness(1) contrast(1); } .container .imgList .img .frag { float: left; height: 460px; width: 25%; background-size: 1226px 460px; opacity: 0; z-index: 0; transform-origin: center right; filter: saturate(0) blur(10px) brightness(.6) contrast(4); transition: transform .6s, opacity .6s, filter .6s ease-out; }

下载按钮动态效果

分析这个效果大概分成几个部分
- 静态按钮
- 点击后按钮宽度变小，然后成圆形
- 按钮变大变小
- 小白球转圈
- 回到圆中心位置，显示“√”
基于分析，静态效果很容易实现。
对于紫色的小球变大变小也很简单。scale即可如果使用了translate属性，需要将translate属性写在scale之前。 @keyframes circle{ 0%,15%,45%,75%{ transform:translate(-50%,-50%) scale(0.8) ; } 30%,60%,90%{ transform:translate(-50%,-50%) scale(1.2) ; } 100%{ transform: translate(-50%,-50%) scale(1) ; } }
小白球旋转 @keyframes dot{ 8%{ transform: scale(0); } 16%{ transform: scale(1) rotate(30deg) translateX(48px); } 95%{ transform: scale(1) rotate(1000deg) translateX(48px); } 100%{ transform: scale(0.125) rotate(1050deg) translate(52px ); } }
点击效果可以使用伪类focus模拟
