这是官方给的布局代码
<view class="section"><view class="section__title">vertical scroll</view><scroll-view scroll-y style="height: 200px;" bindscrolltoupper="upper" bindscrolltolower="lower" bindscroll="scroll" scroll-into-view="{{toView}}" scroll-top="{{scrollTop}}"><view id="green" class="scroll-view-item bc_green"></view><view id="red" class="scroll-view-item bc_red"></view><view id="yellow" class="scroll-view-item bc_yellow"></view><view id="blue" class="scroll-view-item bc_blue"></view></scroll-view><view class="btn-area"><button size="mini" bindtap="tap">click me to scroll into view </button><button size="mini" bindtap="tapMove">click me to scroll</button></view></view><view class="section section_gap"><view class="section__title">horizontal scroll</view><scroll-view class="scroll-view_H" scroll-x style="width: 100%"><view id="green" class="scroll-view-item_H bc_green"></view><view id="red" class="scroll-view-item_H bc_red"></view><view id="yellow" class="scroll-view-item_H bc_yellow"></view><view id="blue" class="scroll-view-item_H bc_blue"></view></scroll-view></view>
在文档上对css没有进行描述，要想横向滚动，首先要先把子元素设置成一行，发现float不能用
要对子元素进行display:inline-block ,容器进行white-space: nowrap;
css如下：
.scroll-view_H{width: 100%;white-space: nowrap; }.scroll-view-item_H{width: 200px;height: 100px;display: inline-block;}
