html - Bootstrap 画廊悬停

Question

我为我的画廊制作了悬停效果。画廊位于 Bootstrap 网格内。悬停本身工作正常，但在某些屏幕尺寸下，叠加层会覆盖图库图像。

有人对此问题有想法、解决方案或提示吗？

举个例子:

Answer 1

叠加层覆盖图库图像，因为覆盖层具有 width:100%; 并且当图像小于其容器的宽度时，叠加层覆盖图库图像，因为宽度为图片

您有 2 个选项可以使图像 width:100% 或者您可以更改 .box 类的样式并删除 width:100%; 并使其成为显示:内联 block ；

.box {
    position: relative;
    cursor: pointer;
    // width: 100%;          // remove this
    display:inline-block;    // add this
    min-height: 100%;
    overflow: hidden;
    margin-bottom: 30px;
}
