移动端rem字体适配示例

虽然很简单，但是为了需要的时候能直接 ctrl + C / ctrl + V ，还是写一下存着。嘿嘿


@media screen and (min- 320px) {
     html {
        font-size: 13.65333px;
    } 
}

@media screen and (min- 360px) {
    html {
        font-size: 15.36px;
    }
}

@media screen and (min- 375px) {
    html {
        font-size: 16px;
    }
}

@media screen and (min- 384px) {
    html {
        font-size: 16.384px;
    }
}

@media screen and (min- 412px) {
    html {
        font-size: 17.5787px;
    }
}

@media screen and (min- 414px) {

 这里以iphone6为例，1rem就是16px，若font-size为12px就是0.667rem，用在字体上还好，要是其他元素也采用rem单位，频繁计算就很麻烦了，以下整理了一份便于计算的↓

@media screen and (min- 320px) {
     html {
        font-size: 8.533px;
    } 
}

@media screen and (min- 360px) {
    html {
        font-size: 9.6px;
    }
}

@media screen and (min- 375px) {
    html {
        font-size: 10px;
    }
}

@media screen and (min- 384px) {
    html {
        font-size: 10.24px;
    }
}

@media screen and (min- 412px) {
    html {
        font-size: 10.99px;
    }
}

@media screen and (min- 414px) {
    html {
        font-size: 11.04px;
    }
}

这样的话，计算起来就容易多了。例如一个盒子分别是100px，123px，字体13px，转成rem就是：10rem, 12.3rem, 1.3rem
