先进行整体布局

首页布局：页眉、主体、页脚、

<div class="home"></div>
<div class="header"></div>
<div class="main>"</div>
<div class="footer"></div>

添加参考线

用轮廓线不会占页面空间

.home>*{
 outline:1px solid red；
}

页面样式重置

样式重置

*{
 margin:0;
 padding:0;
 box-sizing: border-box;
}

html{
 font-size:10px;
}

rem

html{
 font-size:10px;
}

用a链接去除下划线

a{
text-decoration:none;
color:666;
}
li{
list-style:none;
}

恢复字号

在body里面恢复字号16px

body{
 font-size:1.6rem;
 background-color:#f6f6f6;
}

媒体查询

动态设置rem大小
从小到大，移动优先

@meadia screen and(min-width:480px){
html{
   font-size:12px;
}
}
@meadia screen and(min-width:640px){
html{
   font-size:14px;
}
}
@meadia screen and(min-width:720px){
html{
   font-size:16px;
}
}

把以上代码放入rest.css中

rest专门做样式重置的
放入rest后在html中关联起来

<link rel="stylesheet" href="css/reset.css"/>

仿作的网站为单列三行

中间内容会溢出

页眉和页脚是固定的

视口不足，给个最小的高度
view height:视口高度
页面布局直接用grid来写
页眉页脚固定所以给个固定大小

.home{
 min-height：100vh；
 display：grid；
 grid-template-rows：4em 1fr 6rem；
}

中间主体部分

隐藏中间主体部分

.home .main{
 height:calc(100vh-4rem-6rem);
 overflow-y：scroll；
}

头部首页布局

第一部分是个按钮加入字体图标引用

<link rel="stylesheet" href="lib/font_icon/iconfont.css" />

在页眉的div中加入

<span class="iconfont icon-caidan"><span>

加入搜索框加入一个块
在快中加入京东LOGO和搜索图标

<div class="search">
<span class="iconfont icon-jingdong "><span>
<span class="iconfont icon-search"><span>
<from action="">
<input type="search" name="search" value="联想拯救者">
</div>

登录按钮

用button来做也行

<a href="">登录</a>

在css创建header

修改html的头部样式

.home .header {
  background-color: red;
  display: grid;
  grid-template-columns: 5rem 1fr 5rem;
  place-items: center;
  color: #fff;
}
.home .header.icon-caidan {
  font-size: 2.5ren;
  font-weight: bolder;
}
.home .header a {
  color: white;
  font-size: 1.4rem;
}
.home .header .search {
  width: 100%;
  background-color: #fff;
  padding: 0.2em;
  border-radius: 1.5rem;
  display: grid;
  grid-template-columns: auto auto 1fr;
}
.home .header .search form input {
  min-width: 100%;
  outline: none;
  border: none;
  color: #888;
}
.home .header .search .icon-jingdong {
  color: #e43130;
  font-size: 2rem;
  padding: 0 0.5rem;
  place-self: center;
}
.home .header .search .icon-search {
  color: #888;
  font-size: 2rem;
  padding: 0 0.5rem;
  place-self: center;
}

回到html输出：

回到html布局页脚

 <div class="footer">
        <div>
          <span class="iconfont icon-jingdong1"></span>
          <span>京东</span>
        </div>
        <div>
          <span class="icofont icon-fenlei2"></span>
          <span>分类</span>
        </div>
        <div>
          <span class="iconfont icon-social-jingxi"></span>
          <span>惊喜</span>
        </div>
        <div>
          <span class="iconfont icon-gouwuche"></span>
          <span>购物车</span>
        </div>
        <div>
          <span class="iconfont icon-weidengluyonghuicon"></span>
          <span>未登录</span>
        </div>
      </div>
    </div>

.home .footer {
  background-color: #efefef;
  border-top: 1px solid #ddd;
  display: flex;
  place-content: space-around;
}
.home .footer div {
  color: #888;
  display: flex;
  flex-flow: column nowrap;
  /* 垂直水平方向居中 */
  place-items: center;
}
.home .footer div:first-of-type {
  color: red;
}
/* 调整图标大小 */
.home .footer div span:first-of-type {
  font-size: 2.5rem;
}
/* 调整文本大小 */
.home .footer div span:last-of-type {
  font-size: 1.2rem;
}

轮播图写在主体main里面

<div class="main">
        <div class="slider">
          <div class="imgs">
            <a href="" class="active"
              ><img src="static/images/banner.png" alt=""
            /></a>
            <a href=""><img src="static/images/banner.png" alt="" /></a>
            <a href=""><img src="static/images/banner.png" alt="" /></a>
          </div>

同上记得引入css才有效果

<link rel="stylesheet" href="css/slider.css" />

轮播图css代码

.home .main .slider {
  width: 90%;
  margin: 1rem auto 2rem;
}
.home .main .slider img {
  width: 100%;
  border-radius: 1rem;
  margin-top: 1rem;
}
/* 初始化时,将所有轮播图片先全部隐藏,默认只显示第一个 */
/* 注意,轮播图是可点击的,图片在链接元素中,所以只需要设置a标签即可 */
.home .main .slider .imgs a {
  display: none;
}
/* 默认第一个轮播图激活 */
.home .main .slider .imgs a.active {
  display: block;
}
/* 切换按钮容器的样式 */
.home .main .slider .btns {
  /* flex布局,且水平居中,并上移到轮播图底部 */
  display: flex;
  justify-content: center;
  /* 负外距可反向移动元素,这里是向上 */
  margin-top: -2rem;
}
/* 切换按钮 */
.home .main .slider .btns .item {
  height: 0.8rem;
  width: 0.8rem;
  border-radius: 50%;
  background-color: #888;
  margin: 0.2rem;
}
/* 切换按钮鼠标悬停样式 */
.home .main .slider .btns .item:hover {
  cursor: pointer;
}
/* 当前默认激活的按钮样式 */
.home .main .slider .btns .item.active {
  background-color: #e43130;
}

导航区

因为都是字体图标，字体都是可点击。所以用a链接来写。

  <div class="navs">
          <ul class="nav-group active">
            <li>
              <a href=""><img src="static/images/nav/nav-1.png" alt="" /></a>
              <a href="">京东超市</a>
            </li>
            <li>
              <a href=""><img src="static/images/nav/nav-2.png" alt="" /></a>
              <a href="">数码电器</a>
            </li>
            <li>
              <a href=""><img src="static/images/nav/nav-3.png" alt="" /></a>
              <a href="">京东服饰</a>
            </li>
            <li>
              <a href=""><img src="static/images/nav/nav-4.png" alt="" /></a>
              <a href="">京东生鲜</a>
            </li>
            <li>
              <a href=""><img src="static/images/nav/nav-5.png" alt="" /></a>
              <a href="">京东到家</a>
            </li>
            <li>
              <a href=""><img src="static/images/nav/nav-6.png" alt="" /></a>
              <a href="">充值缴费</a>
            </li>
            <li>
              <a href=""><img src="static/images/nav/nav-7.png" alt="" /></a>
              <a href="">9.9元拼</a>
            </li>
            <li>
              <a href=""><img src="static/images/nav/nav-8.png" alt="" /></a>
              <a href="">领券</a>
            </li>
            <li>
              <a href=""><img src="static/images/nav/nav-9.png" alt="" /></a>
              <a href="">领金贴</a>
            </li>
            <li>
              <a href=""><img src="static/images/nav/nav-10.png" alt="" /></a>
              <a href="">PLUS会员</a>
            </li>
          </ul>
        </div>

记得再hetml关联导航区的css

新建navs.css布局导航区

用网格布局来写

.home .main .navs .nav-group {
  display: grid;
  grid-template-columns: repeat(5, 1fr);
}
.home .main .navs .nav-group li a {
  font-size: 1.2rem;
}
.home .main .navs .nav-group li img {
  width: 4rem;
}
.home .main .navs .nav-group li {
  display: grid;
  place-items: center;
}

商品区

代码比较长就不全部复制过来了

<ul class="list">
          <li class="item">
            <a href=""><img src="static/images/items/item1.jpg" alt="" /></a>
            <div class="intro">
              <span>自营</span>
              <span>商品介绍商品介绍商品介绍商品介绍商品介绍...</span>
            </div>
            <div class="price">
              <span class="iconfont icon-renminbi">2877</span>
              <span class="sign">满减</span>
              <span class="other">看相似</span>
            </div>
          </li>
          <li class="item">
            <a href=""><img src="static/images/items/item2.jpg" alt="" /></a>
            <div class="intro">
              <span>自营</span>
              <span>商品介绍商品介绍商品介绍商品介绍商品介绍...</span>
            </div>
            <div class="price">
              <span class="iconfont icon-renminbi">1899</span>
              <span class="sign">满减</span>
              <span class="other">看相似</span>
            </div>
          </li>
          <li class="item">
            <a href=""><img src="static/images/items/item3.jpg" alt="" /></a>
            <div class="intro">
              <span>自营</span>
              <span>商品介绍商品介绍商品介绍商品介绍商品介绍...</span>
            </div>

创建商品区的css，list.css

.home .main .list {
  display: grid;
  grid-template-columns: repeat(2, 1fr);
  gap: 1.5rem;
  padding: 1.5rem;
}
.home .main .list img {
  width: 100%;
  border-radius: 0.5rem;
  padding-bottom: 3rem;
  border-radius: 1rem;
  font-size: 1.3rem;
}
