CSS判断横屏竖屏
@media screen and (orientation: portrait) {
/*竖屏 css*/
}
@media screen and (orientation: landscape) {
/*横屏 css*/
}

JS判断横屏竖屏
//判断手机横竖屏状态：
window.addEventListener("onorientationchange" in window ? "orientationchange" : "resize", function() {
if (window.orientation === 180 || window.orientation === 0) {
alert(‘竖屏状态！‘);
}
if (window.orientation === 90 || window.orientation === -90 ){
alert(‘横屏状态！‘);
}
}, false);
//移动端的浏览器一般都支持window.orientation这个参数，通过这个参数可以判断出手机是处在横屏还是竖屏状态。

// 横屏监听
var updateOrientation = function(){
if(window.orientation==‘-90‘ || window.orientation==‘90‘){
$(‘.landscape-wrap‘).removeClass(‘hide‘);
console.log(‘为了更好的体验，请将手机/平板竖过来！‘);
}else{
$(‘.landscape-wrap‘).addClass(‘hide‘);
console.log(‘竖屏状态‘);
}
};
window.onorientationchange = updateOrientation;
