Question

我有一排缩略图，动画标题以display：flex为中心。单击缩略图按钮时，会出现带有幻灯片显示的模式。关闭模态后，所选图库的缩略图将移位。我已经对此进行了大量的CSS调试，但没有找到任何结论。我正在考虑它的Bootstrap模态JS的副作用或与display有关：flex - display：阻止hover切换。

Answer 1

这是因为在@media screen and (min-width: 1024px)上，您将.cta_box的顶部设置为100％，这将框推到底部，但是与以前的样式相比，您仍然将其底部设置为0。这基本上使盒子的高度为0。因此，其内容将溢出。

模态关闭后背景图像的移动是由于框内容溢出。

修复很容易。只需在overflow: hidden;上添加.cta_box。
