移动端适配JS和CSS

移动端适配一般是两种方式

一JS方式：

setRem();window.addEventListener("orientationchange", setRem);window.addEventListener("resize", setRem);function setRem() {/** 以750*1334的设计稿为例：1rem=40px*/var html = document.querySelector("html");var width = html.getBoundingClientRect().width;html.style.fontSize = width / 18.75 + "px";}

JS方式书写方便，而且适配所有的机型，但是好像会有小数点问题

二CSS方式：

/* 适配 */
@media only screen and (min-width: 320px) {html {font-size: 17.066666px !important;}
}
@media only screen and (min-width: 360px) {html {font-size: 19.2px !important;}
}
@media only screen and (min-width: 375px) {html {font-size: 20px !important;}
}@media only screen and (min-width: 400px) {html {font-size: 21.33333333px !important;}
}
@media only screen and (min-width: 412px) {html {font-size: 21.97333px !important;}
}
@media only screen and (min-width: 414px) {html {font-size: 22.08px !important;}
}@media only screen and (min-width: 480px) {html {font-size: 25.6px !important;}
}
@media only screen and (min-width: 768px) {html {font-size: 40.96px !important;}
}

CSS方式适配比较麻烦，每一个机型都要去手动设置，但是比较准确，小数点问题好像会被解决掉
