This is deployed with the <code>#grid</code> div fluid (that is, it has no Bootstrap <code>.container</code> class). To make it fixed simply add the <code>.container</code> class to it. Use the media queries in <strong>style.css</strong> to change the grid's post widths and margins.

Can this be done with Masonry options? */

gutter: gutter,
itemSelector: '.post',

});
// This code fires every time a user resizes the screen and only affects .post elements
// whose parent class isn't .container. Triggers resize first so nothing looks weird.
jQuery(window).bind('resize', function () {
if (!jQuery('#posts').parent().hasClass('container')) {
// Resets all widths to 'auto' to sterilize calculations
post_width = jQuery('.post').width() + gutter;
jQuery('#posts, body > #grid').css('width', 'auto');
// Calculates how many .post elements will actually fit per row. Could this code be cleaner?
posts_per_row = jQuery('#posts').innerWidth() / post_width;
