Tilz is a simple, lightweight, javascript tool for creating tiled layouts. In other words, a way to fix vertical spacing when using CSS's property float.

To use Tilz, all you need is to wrap your elements inside a container element, then declare a new object as shown in this example:

<div class="container">
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  ...
</div>
<script src="./path/to/tilz.js"></script>

var myTiles = new Tilz("container","item",gutter,time);
myTiles.start();

Where gutter (positive integer) is the spacing between tiles in pixels, and time (positive integer) is the duration of the tiles animation in milliseconds when the layout is refreshed (resizing the window or manually calling the organize() method).

The best way to implement Tilz in this case is to use gutter-less layout and items as wrappers for content elements.

<div class="container">
  <div class="item">
    <div class="content"></div>
  </div>
  <div class="item">
    <div class="content"></div>
  </div>
  <div class="item">
    <div class="content"></div>
  </div>
  ...
</div>

var myTiles = new Tilz("container","item",0,time);
myTiles.start();
