//颜色函数，返回随机色
function c() {
var str = "0123456789abcdef";
var cc = "#";
cc += str.charAt(Math.round(Math.random() * (str.length - 1)));

}
//长度函数，返回随机长度
function long() {
var dd = Math.round(Math.random() * 100);
dd = dd + "%";
return dd;
}
//为p调用随机颜色和随机长度
var ad = document.getElementsByTagName("p");
for (var o of ad) {
o.style.backgroundColor = c();
o.style.color = c();
o.style.width = long();
}
