@media screen
and (max-width:
768px) {
body{
background-color:
red;
}
}
@media screen
and (min-width:
768px)
and (max-width:
992px) {
body{
background-color:
yellow;
}
}
@media screen
and (min-width:
992px)
and (max-width:
1200px) {
body{
background-color:
blue;
}
}
@media screen
and (min-width:
1200px) {
body{
background-color:
aqua;
}
}
不同屏幕大小下显示不同的背景,大体就是这四种屏幕
@media (max-width: @screen-xs-max) { ... } @media (min-width: @screen-sm-min) and (max-width: @screen-sm-max) { ... } @media (min-width: @screen-md-min) and (max-width: @screen-md-max) { ... } @media (min-width: @screen-lg-min) { ... }这个是菜鸟教程里面的,专门为bootstrap准备的。
看那两红色的框就行了,他们两的关系就是差那么个padding-left/right
