如果您想以与非视网膜图像相同的方式显示图像,则需要设置图像的宽度。
这里有一些例子:
这是最小宽度(响应式设计)桌面 css 的示例:
.site-header {
position: relative;
background: url('assets/images/XXXX.jpg') 0px 0px no-repeat;
height: 155px;
background-size: cover;
background-position:center;
}
响应式设计的 Retina
@media
only screen and (-webkit-min-device-pixel-ratio: 2) and (min-width: 768px),
only screen and ( min--moz-device-pixel-ratio: 2) and (min-width: 768px),
only screen and ( -o-min-device-pixel-ratio: 2/1) and (min-width: 768px),
only screen and ( min-device-pixel-ratio: 2) and (min-width: 768px),
only screen and ( min-resolution: 192dpi) and (min-width: 768px),
only screen and ( min-resolution: 2dppx) and (min-width: 768px) {
.site-header
{
position: relative;
background: url('assets/images/GBBO_BG_1536_R.jpg') 0px 0px no-repeat;
height: 148px;
background-size:cover;
}
/* Iphone P */
#header #logo_home {
width: 154px;
height: 102px;
background: url('assets/images/GBBO_logo_1536_R.png') 0px 0px no-repeat;
background-size: 100% auto;
}
}
要移除响应式效果,请移除“and (min-width: 768px)”
