当视口大于图像宽度时,图像居中,但当图像宽度大于视口宽度时,图像向左对齐而不是向中心对齐。我的目标是使图像始终裁剪到视口的宽度,并始终与中心对齐。
body,
html {
margin: 0;
padding: 0;
}
.crop {
width: 100%;
height: 50%;
overflow: hidden;
background-color: red;
}
#cropped-img {
position: relative;
height: 100%;
display: block;
margin: auto;
}
<div class="crop">
<img id="cropped-img" src="http://img1.jurko.net/wall/paper/donald_duck_4.jpg" />
</div>
您可以使用flexbox实现您想要的:
body,
html {
margin: 0;
padding: 0;
}
.crop {
overflow: hidden;
background-color: red;
display:flex;
justify-content:center;
}
<div class="crop">
<img id="cropped-img" src="http://img1.jurko.net/wall/paper/donald_duck_4.jpg" >
</div>
没
关系,我设法使用背景图像属性获得了我需要的确切效果。如果其他人感兴趣,这是我使用的HTML和CSS:
.HTML:
<div class="crop"></div>
.CSS:
body, html {
margin:0;
padding:0;
}
.crop {
width: 100%;
height: 500px;
overflow: hidden;
background-image: url("http://img1.jurko.net/wall/paper/donald_duck_4.jpg");
background-repeat: no-repeat;
background-position: center;
}
尝试为变量值提供占据元素宽度 100%
的图像
body,
html {
margin: 0;
padding: 0;
}
.crop {
width: 100%;
height: 50%;
overflow: hidden;
background-color: red;
text-align: center;
}
#cropped-img {
position: relative;
height: 100%;
width: 100%;
max-width: 100%;
display: block;
margin: 0 auto;
}
<div class="crop">
<img id="cropped-img" src="http://img1.jurko.net/wall/paper/donald_duck_4.jpg" />
</div>
