在 div stretch 内设置背景图片
Set background image inside div stretch
这是我的代码:
#mainwrapper {
font: 10pt normal Arial, sans-serif;
height: auto;
margin: 80px auto 0 auto;
text-align: center;
width: 1000px;
}
/* Image Box Style */
#mainwrapper .box {
border: 2px solid #fff;
cursor: pointer;
height: 200px;
float: left;
margin: 0 auto;
position: relative;
overflow: hidden;
width: 400px;
background-size: cover;
-webkit-box-shadow: 1px 1px 1px 1px #ccc;
-moz-box-shadow: 1px 1px 1px 1px #ccc;
box-shadow: 1px 1px 1px 1px #ccc;
}
#mainwrapper .box img {
width: 100%;
-webkit-transition: all 300ms ease-out;
-moz-transition: all 300ms ease-out;
-o-transition: all 300ms ease-out;
-ms-transition: all 300ms ease-out;
transition: all 300ms ease-out;
}
#mainwrapper .box .caption {
background-color: rgba(0, 0, 0, 0.8);
position: absolute;
color: #fff;
z-index: 100;
-webkit-transition: all 300ms ease-out;
-moz-transition: all 300ms ease-out;
-o-transition: all 300ms ease-out;
-ms-transition: all 300ms ease-out;
transition: all 300ms ease-out;
left: 0;
}
/** Caption 1: Simple **/
#mainwrapper .box .simple-caption {
height: 30px;
width: 200px;
display: block;
bottom: -30px;
line-height: 10pt;
text-align: center;
}
/** Simple Caption :hover Behaviour **/
#mainwrapper .box:hover .simple-caption {
-moz-transform: translateY(-100%);
-o-transform: translateY(-100%);
-webkit-transform: translateY(-100%);
opacity: 1;
transform: translateY(-100%);
}
<div id="mainwrapper">

<div id="box-1" class="box">

我想要做的是将父级 div 中的背景图像设置为拉伸。
我试过#mainwrapper .box img
喜欢
position:absolute;
margin: auto;
max-width: 100%;
max-height: 100%;
但这不起作用。
只需将图片的宽度设置为 100%
#mainwrapper .box img {
width: 100%;
}
或在 css 中为 div 添加 background-image
。
.box {
background-image: url("http://www.sideshowtoy.com/wp-content/uploads/2016/01/marvel-deadpool-sixth-scale-hot-toys-feature-902628.jpg");
background-size:cover;
}
如果您选择此路线,请删除 HTML 中的 <img>
标签。
几件事:
- 你不能在
span
中包含 p
标签
- 在您的
img
中使用 max-width:100%
(如果图像小于容器,则 width:100%
)
- 在你的
#mainwrapper
中使用 max-width
而不是 width
来避免滚动条,容器将是 "resizable",因此响应式工作更容易
- 去掉
background:cover
,因为你根本就没有背景
