Waterfall flow layout is a layout that was very popular before and is now more common.
This kind of uneven-looking multi-column layout focuses on each element, etc. The width is not equal to the height, which is commonly used in picture websites.
As the page scrolls, data blocks will be loaded continuously at the bottom of each column. In theory, it can be loaded infinitely without making the page beautiful.
Pinterest , Huaban.com are relatively mature websites that adopt waterfall flow layout

function waterFall(main, box) { var main = document.getElementById(main); var boxs = main.getElementsByClassName(box); var boxWidth = boxs[0].offsetWidth; //获取每个数据块的宽度
var mainWidh = main.offsetWidth; //获取主容器的宽度

var heightArr = []; //定义一个存放 top 值的数组
for(var i = 0; i < boxs.length; i++) { var boxHeight = boxs[i].offsetHeight; if(i < cols) { //第一行 heightArr.push(boxs[i].offsetHeight);
boxs[i].style.top = '0px';
