    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;
