On my project I have faced with the same problem and I came to the next decision - the best way for me is to go with js, in my case you can have xxx count of block inside container, if there is enough space in 1st row the block from 2nd row goes up to the 1st row, and so on. here is an example http://jsfiddle.net/gVAjN/11/

 $(function() {
  // Call function when DOM is ready
  settingsAlignment();

$(window).resize(function() {
      // Call function on window resize
        settingsAlignment();
    })

$('#new_div').click(function() {
    box_number = $('.element').size();
    box_add = box_number + 1;
    $('.container').append($('
Box'+ box_add + '
'))
    settingsAlignment();
})

function settingsAlignment() {
// calculation of ul's padding-left and li's margin-right
var settingsUl = $('.container');
    settingsLi = $('.element');
    ul_width = settingsUl.outerWidth(true);
    item_width = settingsLi.width();
    min_gap = 7;
    effective_item_width = item_width + min_gap;
    items_in_row = Math.floor((ul_width - min_gap) / effective_item_width);
    gaps_sum = ul_width - items_in_row * item_width;
    new_gaps = gaps_sum / (items_in_row + 1);
    item_margin = Math.floor(new_gaps);
    row_width = (item_width + item_margin) * items_in_row - item_margin;
    console.log(row_width + '= row_width');
    console.log(ul_width + '= ul_width');
    ul_left_padding = Math.ceil((ul_width - row_width) / 2);
    console.log(ul_left_padding + '=ul_left_padding');
    settingsUl.css('padding-left', ul_left_padding + 'px');
    settingsLi.css('margin-right', item_margin + 'px');
  console.log(settingsLi);
 }
});
