如您在以下代码段中所见。项目部分隐藏了一些项目。我用了cssoverflow:scroll；属性我想你可以滚动多少是有限制的。

有什么解决方案可以得到无限滚动深度吗？

Answer 1

从这个 class 中删除 display: flex 属性将修复它。

.projects-grid {
    min-height: 30vh;
    max-height: 50vh;
    width: 90%;
    overflow: scroll;
    overflow-x: hidden;
}

我假设您仍然想使用 display: flex 来使用 justify-content 或 align-items 来对齐您的项目。如果你想这样做，请考虑在你的项目周围包装另一个 <div> 并在其中添加 flex 属性。

overflow:scroll; 属性没有提供足够的滚动深度

overflow:scroll; property is not providing enough scroll depth
