复习回顾——页面布局
如图，需要实现的布局为经典的三列布局（logo、导航、登录注册按钮）。
对于这种情况首先想到的应该是这样的。
也就是说在一个大的容器中，我们在写入一个容器（红色）作为存放绿色容器、蓝色容器、紫色容器 。那么实现起来就很简单了。

<header class="head">
<div class="container">
<div class="logo"></div>
<div class="nav"></div>
<div class="login"></div>
</div>
</header>
|
第一步需要做的就是黑色的容器的宽度设置为100%,这是为了给里边的元素实现居中。
第二步就是实现红色容器的居中并且设置宽高。这一步也很简单，因为黑色的已经有了宽度，那么只需要进行外边距左右自动即可。

width: 1200px;
height: 90px;
margin: 0 auto;
}
|
第三步即调整绿色容器、蓝色容器、紫色容器 的位置问题
实现之前，应首先设置他们的宽高，为了方便同时设置上背景色，方便调整。

.head .container .logo {
width: 80px;
height: 90px;
background-color: green;
}
.head .container .nav {
width: 420px;
height: 90px;
background-color: blue;
}
.head .container .login{
width: 240px;
height: 90px;
background-color: purple;
}
|
第一种方案：通过浮动实现
这种方法很简单。
第一步：左侧与中间设置为浮动
第二步：调整中间距离左侧的距离（margin-left）
第三步：右侧使用右浮动即可。

.head .container .login{
float: right;
}
|
参考演示：https://antmoe.gitee.io/project/2020/03/23/center-1.html
第二种方案：定位
这种方法也很容易理解。
第一步：为父级容器开启相对定位（因为不脱离文档流）
第二步：为每个子集元素（绿蓝紫div）设置绝对定位。
第三步：利用top、left调整每个div的位置。

}

第三种方案：利用表格
这种方法也很简单。
第一步：将父级的显示为表格
第二步：子级显示为单元格

.head .container {
display: table;
}
.head .container .login,
.head .container .logo,
.head .container .nav {
display: table-cell;
}
|
但是这个方法存在一些问题,如图，使用表格后会默认将其填充满，无法使用宽高进行设置。解决方法也很简单，使用内边距即可解决位置问题。因为不需要使用背景色，所以在效果上是看不出来问题的。
参考演示：https://antmoe.gitee.io/project/2020/03/23/center-3.html
第四种方案：外边距
这种方法简单暴力。利用margin-top、margin-left即可调整各元素的位置。

}

这种方法利用行内块级元素的特性可以实现。

第四步就是该在这些元素中填充内容了。
实现片刻网的导航栏
复习了上面的布局后很容易实现这个效果。

实现聚焦图片
参考演示：https://antmoe.gitee.io/project/2020/03/23/index.html
聚焦图片的实现最简单的实现方式就是通过表格来实现，通过图片可以很容易想到八个方格，其中左边四个合并显示为一个。其他四个分别显示。
所以我们的html可以为

当然了，也可以将图片设置为浮动，然后在配合外边距也能达到效果。

实现页面其他内容
页面的基础布局无需过多说明。只是一些细节上的问题。
参考地址：https://antmoe.gitee.io/project/2020/03/24/index.html
关于底部微信二维码
微信二维码案例很简单，只是利用了一个鼠标悬停即可。
大概思路：将二维码内容作为备悬停图标的子元素，当鼠标悬停时找到子元素并为其设置样式即可。
至于底部的小三角可以加一个div为其设置边框即可实现。
div 的宽高为 0
设置边框的宽度
设置边框样式
设置颜色
border-color: white white white black;/* 左边为黑色 */

关于登录框
由于不会用到js所以html结构就显得尤为重要。至于弹出来的框框就比较简单了。姑且用以下结构。
1
2
3
| <div class="login-dialog">
<div class="close-login-box"></div>
</div>
|
然后通过对某个标签模拟点击（focus选择器）来弹出这个登录框。那么接下来，便遇到了一个问题：通过点击注册按钮来将上边的结构显示出来，那么点击的这个元素应该在哪呢？
很简单要想控制一个元素最简单的方法就是写在元素内部，但因为登录从逻辑上应该是全局的，不应该作为按钮的子级。所以这个登录框无疑是要与登录注册按钮的容器是平级的。
所以我们需要将登录框内的登录按钮拿出来那么也就有了

</div>
</div>
</div>
<button class="login-focus">登录 / 注册</button>
<div class="login-dialog">
<div class="close-login-box"></div>
</div>
|
如此一来便可以了。

图片叠层效果
效果展示如图：
伪元素实现
使用伪元素首先要搞清楚的就是伪元素的层级关系。伪元素与标签的层级关系是：after>before>标签元素
我们可以先做一个小demo做个测试。

<title>伪元素层级关系测试</title>
<style>
.test {
width: 150px;
height: 150px;
background-color: lightcoral;
margin: 150px auto;
position: relative;
}
.test::before {
content: "这是before元素";
width: 150px;
height: 150px;
background-color: lightyellow;
position: absolute;
left: 70px;
}
.test::after {
content: "这是after元素";
width: 150px;
height: 150px;
background-color: lightblue;
position: absolute;
left: 160px;
}
</style>
</head>
<body>
<div class="test">这是标签</div>
</body>
</html>

如果很清晰的可以看到三个div的层级关系。标签元素在最下边，标签元素的上方是before，在上边就是after元素了。
既然搞明白了他们的层级关系，那么接下来利用为元素实现层叠图片效果就很容易了。
效果中存在三张尺寸不同的图。那么最小的自然要用标签做了，做大的用after。这样就可以避免给伪元素调整层级的坑了。

利用图片元素实现
利用图实现较为简单。因为图片可以对每一张单独设置，而无需考虑层级问题。

轮播图示例
演示地址：https://antmoe.gitee.io/project/2020/03/25/slide.html
实现思路
两侧旁的按钮可以参考2020-03-17小米轮播图示例。
主要是利用checked伪类判断那一个被选中，然后切换图片。
动画效果方面：首先默认布局应该是中间的变大，左右一边一个。
当被选中后，那么移动到中间，并且原来放大的图移动到右边，右边移动到左边。这样实现一个反复的过程即可。
所以实现起来就很简单了。首先调整好默认位置

.imgList img:nth-of-type(3) {

其次就是设置点击时的样式

轮播图静态布局
一种是比较常规的2d布局。也就是通过定位的方式将三张图片排列开，然后通过层级控制要显示的图片为最高层级。并设置宽高。

另一种方法就是使用3d的方法实现布局。为父级设置perspective属性后，利用translateZ控制图的大小。
