Please help me out.

function randomFromTo(from, to){
            return Math.floor(Math.random() * (to - from + 1) + from);
        }

        function moveRandom(obj) {
            /* get container position and size
             * -- access method : cPos.top and cPos.left */
            var cPos = $('#container').offset();
            var cHeight = $('#container').height();
            var cWidth = $('#container').width();

            // get box padding (assume all padding have same value)
            var pad = parseInt($('#container').css('padding-top').replace('px', ''));

            // get movable box size
            var bHeight = obj.height();
            var bWidth = obj.width();

            // set maximum position
            maxY = cPos.top + cHeight - bHeight - pad;
            maxX = cPos.left + cWidth - bWidth - pad;

            // set minimum position
            minY = cPos.top + pad;
            minX = cPos.left + pad;

            // set new position         
            newY = randomFromTo(minY, maxY);
            newX = randomFromTo(minX, maxX);

            obj.animate({
                top: newY,
                left: newX
                }, 10000, function() {
          moveRandom(obj);
            });
        }
$('.latestblock').each(function() {
moveRandom($(this));
});
