Bootstrap 3 中的全角背景图片
Full-width background image in Bootstrap 3
我可以在 Bootstrap 3 中创建全角图像背景。可以在此处显示示例:
body,
html {
height: 100%;
}
body {
padding-top: 50px;
}
.full {
padding: 0 !important;
margin: 0 auto !important;
background-size: cover;
overflow: hidden;
}
.wide {
width: 100%;
height: auto;
}
.logo {
color: #fff;
font-weight: 800;
font-size: 14pt;
padding: 25px;
text-align: center;
}
.line {
padding-top: 20px;
white-space: no-wrap;
overflow: hidden;
text-align: center;
}

当页面显示为桌面版时,图像会显示为覆盖整个区域。
当页面显示移动设备时,所有图像现在都显示为缩小。
这是什么行为?如何使移动视图中的图像看起来与桌面版中显示的图像相似?
这与响应式成像有关吗?
谢谢

这是由 cover
的标准行为引起的。如果您将桌面浏览器的大小调整为类似纵向的大小,您就会明白我的意思。
一种选择是使用媒体查询,这样当以纵向模式查看页面时,它看起来会好一些。
