如何给 block 元素添加滚动条？
我使用了overflow-y:scroll，但它立即创建了一个滚动条。我想在我的 div 达到特定高度后滚动。
最佳答案
您应该使用overflow-y: auto在达到元素的高度后滚动。
autoDepends on the user agent. If content fits inside the padding box, it looks the same as visible, but still establishes a new block-formatting context. Desktop browsers provide scrollbars if content overflows. - MDN
Whereas
scrollContent is clipped if necessary to fit vertically in the padding box. Browsers display scrollbars whether or not any content is actually clipped. (This prevents scrollbars from appearing or disappearing when the content changes.) Printers may still print overflowing content. - MDN
