我使用bootstrap并且在图像上覆盖标题时出现问题,标题div无法放入框中,如下所示:
HTML:
<div class="col-sm-4">
<a href="#">
<img src="images/upload/projects/21/wolf.jpg" class="img-responsive" alt="" />
<div class="desc">
<p class="desc_content">The pack, the basic unit of wolf social life.</p>
</div>
</a>
</div>
<div class="col-sm-4">
<a href="#">
<img src="images/upload/projects/21/cake.png" class="img-responsive" alt="">
<div class="desc">
<p class="desc_content">The pack, the basic unit of wolf social life.</p>
</div>
</a>
</div>
CSS:
div.desc{
position: absolute;
bottom: 0px;
width: 100%;
background-color: #000;
color: #fff;
opacity: 0.5;
filter: alpha(opacity=50);
}
SOLUTION:
感谢@himanshu解决了这个问题。
div.desc{
background-color: #000;
bottom: 0;
color: #fff;
left: 0;
opacity: 0.5;
position: absolute;
width: 100%;
}
.fix{
width: 100%;
padding: 0px;
}

我认为问题在于放置而不是叠加,div.desc
是绝对的,而图像是它的兄弟。因此,叠加层不会跟随图像,它只会跟随锚标记或您的div.wrapper
。
从我所看到的是,在锚点或包装器中的图像或填充上有一个边距。
最佳解决方案是将desc
和图像放在另一个div
中,宽度为100%,填充为0。
<div class="col-sm-4 wrapper">
<a href="#">
<div class="fix">
<img src="images/upload/projects/21/wolf.jpg" class="img-responsive" alt="" />
<div class="desc">
<p class="desc_content">The pack, the basic unit of wolf social life.</p>
</div></div>
</a>
</div>
CSS:
.fix{width:100%; padding:0px;}

试试这个
<div class="wrapper">
<div class="">
<img src="images/upload/projects/21/wolf.jpg" class="img-responsive" alt="" >
</div>
<div class="desc_content" style="">The pack, the basic unit of wolf social life.</div>
</div>
<div class="wrapper">
<div class="">
<img src="images/upload/projects/21/wolf.jpg" class="img-responsive" alt="" >
</div>
<div class="desc_content" style="">The pack, the basic unit of wolf social life.</div>
</div>
CSS
div.desc_content {
background-color: #000;
color: #FFF;
font: bold 11px verdana;
padding-left: 10px;
padding-top: 7px;
height: 23px; opacity: 0.7;
position: relative;
top: -30px;
}
div.wrapper{
float: left;
position: relative;
margin: 10px;
}

对于试图在Bootstrap中覆盖图片标题的其他人,请考虑使用轮播字幕。
见这里:http://www.w3schools.com/bootstrap/bootstrap_carousel.asp
glob('/images/*');

将此属性用于div.desc类
div.desc{
position: absolute;
bottom: 0;
background-color: #000;
color: #fff;
opacity: 0.5;
left:0; /** new **/
right:0; /** new **/
filter: alpha(opacity=50);
}

这对我有用。这样,您将在图像底部找到标题。
<div class="container-fluid">
<img src="someimg.jpg" class="img-fluid " alt="Patience">
<div class="carousel-caption d-block">
<h1>Some label</h1>
<p>Nulla vitae elit libero, a pharetra augue mollis interdum.</p>
</div>
</div>
如果您希望它位于顶部,请在CSS中执行以下操作:
.carousel-caption{
top:0;
bottom:auto;
}
