scroll-view给出百分比高度为什么没有反应?
我想用小程序写一个音乐播放的界面,其中歌词滚动这一块单独包装了组件。其中scroll-view给出70%的高度并没有反应,歌词甚至翻到了第二页,引用这个的页面,这一块没什么样式限制。现在的截图如下,我希望把歌词保持在黄色框内,谢谢围观和意见!
components/lyric/lyric.wxml:
<scroll-view hidden="{{isLyricShow}}" class="lyric-scroll" scroll-y scroll-top="{{scrollTop}}" scroll-with-animation="true">
<view class="lyric-panel">
<block wx:for="{{lrcList}}" wx:key="item">
<view class="lyric {{index == nowLyricIndex?'hightlight-lyric': ''}}">{{item.lrc}}</view>
</block>
</view>
</scroll-view>
components/lyric/lyric.wxml:
.lyric-scroll {
width: 100%;
height: 70%;
color: #ccc;
font-size: 32rpx;
}
.lyric-panel {
position: relative;
top: 50%;
}
.lyric {
min-height: 64rpx;
}
.hightlight-lyric {
color: #d43c33;
}
