微信小程序scroll-view

scroll-view

使用scroll-view可滚动到对应区域,
注意: 使用竖向滚动时，需要给scroll-view一个固定高度，通过 WXSS 设置 height。

效果图

下图： 标题采用scroll-x横向滚动，内容采用scroll-y纵向滚动，当点击某个分类时滚动到对应区域

wxss

以下样式可通过Webstorm编译为wxss

.scrollViewWrap {
    .cagetory-fixed-x {

        position: fixed;
        top: 0;
        left: 0;

        line-height: 80rpx;
        width: 100%;
        white-space: nowrap;
        text {
