Andrews answer is amazing! I was searching for a solution and finally got it... As Andrew wrote by positioning.. Here my JS snippet. Not perfect, but the right direction. Thanks Andrew!

var tilename = 6;

for (var i = 0; i < document.querySelectorAll('#tiles .t').length; i++) { 
    document.getElementsByClassName("t"+tilename)[0].style.top = document.getElementsByClassName("t"+(tilename-5))[0].offsetHeight + 10;
    tilename += 1;
}

Answer 2

Its simple how it works: Here, I wrote my own in a matter of minutes. http://jsfiddle.net/92gxyugb/1/

coffescript

tiles = $('.tiles .t')
container = $('.tiles').width()
width     = $('.tiles .t:first').width()
columns_height = {}
columns   = Math.floor container / width
space     = container % width 
space     = space / (columns-1)

for tile,i in tiles
  column_index = i % columns
  columns_height[column_index] ?= 0
  sp = switch column_index 
    when 0 then 0
    when columns then 0
    else 
      space * column_index
  $(tile).css
    top: columns_height[column_index]
    left: (column_index * width)+sp
  columns_height[column_index] += $(tile).height()+space

max_height = 0
for k,v of columns_height
  if v > max_height  
    max_height = v
$('.tiles').height max_height-space

html

<div class='tiles'>
  <div class='t t1'></div>
  <div class='t t2'></div>
  <div class='t t3'></div>
  <div class='t t4'></div>
  <div class='t t5'></div>
  <div class='t t6'></div>
  <div class='t t7'></div>
  <div class='t t8'></div>
  <div class='t t9'></div>
  <div class='t t10'></div>
  <div class='t t11'></div>
  <div class='t t12'></div>
  <div class='t t13'></div>
  <div class='t t14'></div>
  <div class='t t15'></div>
  <div class='t t16'></div>
</div>

css

.tiles {position: relative; width: 500px; background: rgb(140,250,250); }
.t { position: absolute; width: 87px; background: rgb(100,100,100); }
.t1 { height: 100px; }
.t2 { height: 140px; }
.t3 { height: 200px; }
.t4 { height: 180px; }
.t5 { height: 120px; }
.t6 { height: 150px; }
.t7 { height: 180px; }
.t8 { height: 200px; }
.t9 { height: 120px; }
.t10 { height: 160px; }
.t11 { height: 210px; }
.t12 { height: 160px; }
.t13 { height: 150px; }
.t14 { height: 150px; }
.t15 { height: 130px; }
.t16 { height: 170px; }

Answer 3

Having looked at all options, I ended up implementing the layout similar to Pinterest in this way:

All DIVs are:

div.tile {
    display: inline-block;
    vertical-align: top;
}

This makes them position in rows better than when they are floated.

Then when the page is loaded, I iterate all DIVs in JavaScript to remove gaps between them. It works acceptably well when:

1. DIVs are not very different in height.
2. You don't mind some minor violations of ordering (some elements that were below can be pulled up above).
3. You don't mind the bottom line being of different height.

The benefit of this approach - your HTMLs make sense for search engines, can work with Javascript disabled/blocked by firewall, the sequence of elements in HTML matches the logical sequence (the newer items before older). You can see it's working at http://SheepOrPig.com/news

Answer 4

Check out JQuery Masonry, it will be the simplest way to achieve the layout you want. http://masonry.desandro.com/

I did some reading of Pinterest's javascript a few months ago to figure this out myself. In short, they don't do it with CSS at all. They position all of their boxes/pins dynamically by iterating through them all, calculating the height, and dropping it at the bottom of whichever column that has the shortest height at the moment (adding that box's height to it). Basically, there's no trick to it, it's just Javascript.

Answer 5

Css can't actually do that in the way you want it to. Javascript, like this example, can.

Due to how rows of floated or inline-blocked content behave, css isn't right for the job. You'd have to dynamically generate vertical columns of content and place them side by side, meaning you'd have to fight to get current content at the top. It would be kind of a pain, really. You'd also lose the responsiveness to window width.

Answer 6

You can now actually do it with css3

.three-col {
   -moz-column-count: 3;
   -moz-column-gap: 20px;
   -webkit-column-count: 3;
   -webkit-column-gap: 20px;
 }
