核心代码：

responsive_waterfall.js

(function() {
  var Waterfall = function(opts) {
    var minBoxWidth;
    Object.defineProperty(this, 'minBoxWidth', {
      get: function() { return minBoxWidth; },
      set: function(value) {
        if(value  1000) value = 1000;
         
        minBoxWidth = value;
      }
    });
 
    opts = opts || {};
    var containerSelector = opts.containerSelector || '.wf-container';
    var boxSelector = opts.boxSelector || '.wf-box';
 
    // init properties
    this.minBoxWidth = opts.minBoxWidth || 250;
    this.columns = [];
    this.container = document.querySelector(containerSelector);
    this.boxes = this.container ? 
      Array.prototype.slice.call(this.container.querySelectorAll(boxSelector)) : [];
 
    // compose once in constructor
    this.compose();
 
    // handle the image or something which might change size after loaded
    var images = this.container.querySelectorAll('img'), that = this;
    var clr;
    for (var i = 0; i  0) {
      // create column div
      this.columns = [];
      var width = (100 / num) + '%';
      while(num--) {
        var column = document.createElement('div');
        column.className = 'wf-column';
        column.style.width = width;
        this.columns.push(column);
        this.container.appendChild(column);
      }
    }
  }
 
  // get the index of shortest column
  Waterfall.prototype.getMinHeightIndex = function() {
    if(this.columns && this.columns.length > 0) {
      var min = this.columns[0].clientHeight, index = 0;
      for (var i = 1; i  -1) {
      var column = this.columns[columnIndex];
      column.appendChild(elem);
    }
  }
 
  window.Waterfall = Waterfall;
})()
