flex 布局 实现电商页面商品展示floor

            有了上一篇,对flex的初次使用,心里痒痒的试着,实现了电商首页,商品展示的floor,先看下效果:

             要实现首先是对组件构件的拆解,拆解如下:

            页面布局如下:            

<div class="floor">
    <div class="floor-wrap">
        <div class="floor-first">
            <span class="floor-title">休闲零食</span>
            <span>|</span>
            <span class="floor-title-dec">精选美味 超值好货</span>
        </div>
        <div class="floor-second">
            <div class="floor-second-left">
                <img src="https://img-b2b.gznb.com/b2c/132202877794914304.jpg"/>
            </div>
            <div class="floor-second-right">
                <div class="product-show">
                    <div style=" 200px;height: 200px">
                        <div class="product-show-pic"
                             style='background-image: url("https://img-b2b.gznb.com/b2c/133315103138254848.jpg")'></div>
                    </div>
                    <div class="product-show-desc">
                        <span class="title" style="font-size: 14px; color: rgb(74, 74, 74);">陕西省宝鸡市灵山薄壳核桃原味500g</span>
                        <span class="price" style="font-weight: 600;">¥23.8 </span>
                    </div>
                    <div class="cart-button">

　      flex 弹性布局,在实现子元素对齐方式,和排列顺序上很方便!
