Question

我已经在图像背景上创建了一个叠加层。但我无法在该叠加层上添加过渡效果。我想给予（过渡：所有.3s轻松;）叠加的过渡。哪个适用于所有h3，文本和背景叠加。

谢谢。

抱歉我的英语不好。

您无法添加到display:none;规则的转换。您必须将所有这些更改为opacity，如下所示。请注意，这里只包含已更改的代码：

.work_slider:hover .slider_detail h3,
.work_slider:hover .slider_detail p
{
    opacity: 1;
}
.work_slider:hover .slider_overlay
{
    opacity: .85;
}
.slider_overlay
{
    transition: all .3s ease;
    opacity: 0;
}
.slider_detail h3
{
    transition: all .3s ease;
    opacity: 0;
}
.slider_detail p
{
    transition: all .3s ease;
    opacity: 0;
}
