jQuery Isotope — Centered and Fluid/Responsive

Question

I am asking a question about Isotope

It is a great plugin for jQuery.

I have been playing with it for a while now, but I don\'t know enough about javascript

This jsfiddle will probably solve your problem: http://jsfiddle.net/schmidjon/6Z3sn/. It's a simple extension to Isotope with breakpoints:

(function ($) {
var $container = $('.example'),
    colWidth = function () {
        var w = $container.width(), 
            columnNum = 1,
            columnWidth = 0;
        if (w > 1200) {
            columnNum  = 5;
        } else if (w > 900) {
            columnNum  = 4;
        } else if (w > 600) {
            columnNum  = 3;
        } else if (w > 300) {
            columnNum  = 2;
        }
        columnWidth = Math.floor(w/columnNum);
        $container.find('.item').each(function() {
            var $item = $(this),
                multiplier_w = $item.attr('class').match(/item-w(\d)/),
                multiplier_h = $item.attr('class').match(/item-h(\d)/),
                width = multiplier_w ? columnWidth*multiplier_w[1]-4 : columnWidth-4,
                height = multiplier_h ? columnWidth*multiplier_h[1]*0.5-4 : columnWidth*0.5-4;
            $item.css({
                width: width,
                height: height
            });
        });
        return columnWidth;
    },
    isotope = function () {
        $container.isotope({
            resizable: false,
            itemSelector: '.item',
            masonry: {
                columnWidth: colWidth(),
                gutterWidth: 4
            }
        });
    };
    isotope();
    $(window).smartresize(isotope);
}(jQuery));
