var html = document.getElementById("html"); // 获取html元素
var add = 0; //初始化一个变化值
add = (winw - 320)*0.0625; //经过测试宽度每增加1px，font-size的值就增加0.0625px
//用得到屏幕的宽度减去320 计算出 大于320多少宽度 最后得到font-size需要自动设置为多少
if (add > 13.75) {
add = 13.75;
}
//做个判断 由于最大的font-size为33.75px 所以这里我就直接用13.75来判断了
html.style.fontSize = 20 + add + 'px';
}
