My Blueprint CSS doesn't work with an uneven number of columns

Question

I am using Blueprint CSS on a Rails app. I am making this a 4-column layout with a box around each item. If I have 4 items or 8 items, then everything is fine and I have 2 rows of products. If I have a 9th product or anything not divisible by 4, then the rows and items become disjointed and spills over to the next column. Does anyone know what the problem is?

div.four-column {
    -moz-column-count: 4;
    -webkit-column-count: 4;
    column-count: 4;
    -moz-column-width: 10em;
    -webkit-column-width: 10em;
    column-width: 10em;
    width: 910px;
}

<ul>
  <% @products.each do |product| %>
    <li class="box">
      <%= link_to product.name, product_path(:id) %></br>
      <%= product.price %>
    </li>
  <% end %>
</ul>

Answer 1

mmm a quick fix might be do just do something like so

<% @count_diff = @products.divmod(4) >
<ul>
  <% @products.each do |product| %>
    <li class="box">
      <%= link_to product.name, product_path(:id) %></br>
      <%= product.price %>
    </li>
  <% end %>
  <% if @count_diff[1] > 0 %>
    <% @count_diff[1].each do |empties| %>
      <li class="box">&nbsp;</li>
    <% end %>
  <% end %>
</ul>

At least i think that's the right code :-) i'm still learning myself. but basically the hack i've provided will just fill in "empty" li tags to balance it all out. So if you have 9 productions it'll make 3 extra empty li's.

There's probably a more "ruby way" of doing it.
