With the following code(from stackoverflow) it's possible to change one colummn size. I want to change at least two.


<div class="col-md-2">
<span class="glyphicon glyphicon-menu-hamburger"></span>
Some content


$('.glyphicon-menu-hamburger').click(function() {
// Find parent with the class that starts with "col-md"
// Change class to "col-md-3"
.toggleClass('col-md-2 col-md-1')
// Find siblings of parent with similar class criteria
// - if all siblings are the same, you can use ".siblings()"
// Change class to "col-md-2"

Check this:

  var columns_container = $(".dynamic-columns");
  if (!columns_container.hasClass("expanded")) {
    $(".dynamic-columns .col:first").removeClass("col-xs-2");
    $(".dynamic-columns .col:first").addClass("col-xs-1");
    $(".dynamic-columns .col:last-child").removeClass("col-xs-8");
    $(".dynamic-columns .col:last-child").addClass("col-xs-9");
  else {
    $(".dynamic-columns .col:first").removeClass("col-xs-1");
    $(".dynamic-columns .col:first").addClass("col-xs-2");
    $(".dynamic-columns .col:last-child").removeClass("col-xs-9");
    $(".dynamic-columns .col:last-child").addClass("col-xs-8");
button {
  position: absolute;
  top: 15px;
  left: 15px;
  z-index: 10;

h4 {
  text-align: center;  

.main-container {
  margin-top: 50px; 

.col {
  background-color: #ccc;
    <link href="" rel="stylesheet">
    <script src="">    </script>
    <div class="container-fluid main-container">
      <div class="row dynamic-columns">
        <div class="col-xs-2 col">
          <h4>First Column</h4>
        <div class="col-xs-2 col">
          <h4>Second Column</h4>
        <div class="col-xs-8 col">
          <h4>Third column</h4>
