想要以绝对子值响应父div高度

Question

我使用html和css3创建了幻灯片。但问题是，当我为子内容设置绝对值时，父div高度不起作用，并且还希望根据图像高度响应高度。

这是我的代码

/*slideshow start*/
/* fade slider */
.slides {
height:100%;
position:relative;
min-width: 100%;
//top:-110px;
overflow:hidden;
border: solid 1px #000;
}
.innerdiv
{
	width:100% !important;
	height:100% !important;
	background-size: cover !important;
}
.slides ul {
list-style:none;
position:relative;
height:auto;
margin:0px;
padding:0px;
padding-bottom:0px !important;
margin-bottom:0px !important;
}


/* keyframes #anim_slides */
@-webkit-keyframes anim_slides {
0% {
opacity:0;
}
6% {
opacity:1;
}
24% {
opacity:1;
}
30% {
opacity:0;
}
100% {
opacity:0;
}
}
@-moz-keyframes anim_slides {
0% {
opacity:0;
}
6% {
opacity:1;
}
24% {
opacity:1;
}
30% {
opacity:0;
}
100% {
opacity:0;
}
}
.slides ul li {
opacity:0;
position:absolute;
top:0;
width:100%;
height:auto;
padding-bottom:0px !important;
margin-bottom:0px !important;

您是否尝试从.slides类中删除overflow: hidden？这至少使您的幻灯片可见，并可能解决您的问题。
