Question

如何用浅绿色包裹#left＆＃34;滚动内容＆＃34;向下滚动时容器到页面底部？当没有＆＃34;滚动内容＆＃34;在左栏中，它也应该被拉伸100％的页面。我认为固定容器下的右栏也应遵循相同的规则。

.wrapper,
html,

.wrapper {

我删除了多余的块和样式。这是最小的HTML和CSS：

fun createCircleBitmapWithTextInside(context: Context, @DrawableRes drawableId: Int, text: String = "POI"): Bitmap{
            val scale = context.resources.displayMetrics.density

            var bitmap = getBitmap(context, drawableId)//BitmapFactory.decodeResource(res, drawableId)
            var bitmapConfig = bitmap.config ?: Bitmap.Config.ARGB_8888
            // resource bitmaps are imutable,
            // so we need to convert it to mutable one
            bitmap = bitmap.copy(bitmapConfig, true)

            val canvas = Canvas(bitmap)
            val paint = Paint(ANTI_ALIAS_FLAG)
            paint.color = ResourceUtils.getColor(context, R.color.white)
            paint.textSize = (18 * scale)
            paint.setShadowLayer(1f, 0f, 1f, Color.WHITE)
            paint.style = Paint.Style.FILL
            paint.textAlign = Paint.Align.CENTER

            val bound = Rect()
            paint.getTextBounds(text, 0, text.length, bound)
            val x = (canvas.width.toFloat() /2)
            // x - point to the center of width
            val y = canvas.height / 2 - (paint.descent() + paint.ascent()) / 2

/*            Timber.d("bitmap.width:${canvas.width} \tbound.width:${bound.width()} \tx:$x")
            Timber.d("bitmap.height:${canvas.height} \tbound.height:${bound.height()} \ty:$y")*/

            canvas.drawText(text, x, y, paint)
            return bitmap
        }

body {
  margin: 0;
  display: flex;
  flex-direction: column;
  min-height: 100vh;
}

.content {
  display: flex;
  flex: 1;
}

nav {
  height: 60px;
  background: tomato;
  position: fixed;
  top: 0;
  width: 100%;
}

#left {
  display: flex;
  background: lightgreen;
  flex: 0 0 40%;
  flex-direction: column;
}

#right {
  display: flex;
  flex: 0 0 60%;
}

#fixed {
  position: fixed;
  background: aqua;
  top: 60px;
  width: 60%;
  height: calc(100vh - 60px);
}

如何在滚动时将列内容包装到底部？
