1.判断是否是IPhoneX手机
let isIphone = /iphone/gi.test(window.navigator.userAgent) let windowW = window.screen.width let windowH = window.screen.height let pixelRatio = window.devicePixelRatio let isIPhoneX = isIphone && pixelRatio && pixelRatio === 3 && windowW === 375 && windowH === 812 let isIPhoneXSMax = isIphone && pixelRatio && pixelRatio === 3 && windowW === 414 && windowH === 896 let isIPhoneXR = isIphone && pixelRatio && pixelRatio === 2 && windowW === 414 && windowH === 896 if (isIPhoneX || isIPhoneXSMax || isIPhoneXR) { // 底部增加fix-iphonex-bottm 样式 $(".contact-box").addClass('fix-iphonex-bottom') // 底部增加iphone-footer-bg样式 初始none,条件满足block $(".iphone-footer-bg").addClass('iphonexshow') }
2.增加fix-iphonex-bottom样式
.fix-iphonex-bottom { bottom: 34px !important;}
如果想更改IPhoneX底部34像素的背景颜色怎么办呢？
3.增加iphone-footer-bg样式
.iphone-footer-bg { height: 34px; background: #6D6D6D; width: 100%; position: absolute; bottom: -33px; display: none;}.iphonexshow { display: block !important;}
