js

$(document).ready(function(e) {     var months = [      {month:'january', state:''},     {month:'feburary', state:''},     {month:'march', state:''},     {month:'april', state:''},     {month:'december', state:''}];     $(months).each(function(index, element){         element.state == 'current' ?         activemonth = 'activemonth':activemonth = '';         $('.monthsholder').append('<article class="calendermonth '+activemonth+'">\         <header class="calendermonth_header">'+element.month+'</header>\         </article>');     }); }); 

html

<section class="app_section app_section_calender hide center">   <header class="app_section_header">calender   <section class="monthsholder"  align="center"></section> </section> 

how make smaller boxes fill remaining spaces?

add float: left activemonth class :

.activemonth {   float: left;   height: 340px;   width: 340px; }
