Web组件如何实现嵌套滑动，如何实现web控件的自适应高度

import web_webview from '@ohos.web.webview'; 
 
@Entry 
@Component 
export struct NestedScroll { 
  private scrollerForScroll: Scroller = new Scroller() 
  controller: web_webview.WebviewController = new web_webview.WebviewController(); 
  // scroll竖向的滚动 
  @State ScrollDirection: ScrollDirection = ScrollDirection.Vertical 
  title = '2023落下帷幕，一起迎接2024年***********' 
  review = '评论' 
  context = '一起迎接2024年，*********' 
  list = [0, 0, 0, 0] 
 
  build() { 
    Flex() { 
      Scroll(this.scrollerForScroll) { 
        Column({ space: 5 }) { 
          Text(this.title).fontSize(40).padding(40) 
          List() { 
            ForEach(this.list, () => { 
              ListItem() { 
                Text(this.context).fontSize(16) 
              }

          Web({ src: $rawfile("scroll.html"), controller: this.controller }) 
            .nestedScroll({ 
              scrollForward: NestedScrollMode.SELF_FIRST, 
              scrollBackward: NestedScrollMode.SELF_FIRST
