<!-- Portfolio Gallery Grid -->
<div class="row">
  <div class="column nature">
    <div class="content">
      <img src="/w3images/mountains.jpg" alt="Mountains" style="width:100%">

      <p>Lorem ipsum dolor..</p>
    </div>
  </div>
  <div class="column nature">
    <div class="content">
      <img src="/w3images/nature.jpg" alt="Nature" style="width:100%">
      <h4>Forest</h4>
      <p>Lorem ipsum dolor..</p>
    </div>

  <div class="column cars">

  <div class="column people">
    <div class="content">
      <img src="/w3images/people3.jpg" alt="People" style="width:100%">
      <h4>Woman</h4>
      <p>Lorem ipsum dolor..</p>
    </div>
  </div>
<!-- END GRID -->
</div>


Step 2) Add CSS:

Example

* {
    box-sizing: border-box;
}

body {
    background-color: #f1f1f1;
    padding: 20px;
    font-family: Arial;
}

/* Center website */
.main {
    max-width: 1000px;
    margin: auto;
}

h1 {
    font-size: 50px;
    word-break: break-all;
}

.row {
    margin: 8px -16px;
}

/* Add padding BETWEEN each column (if you want) */
.row,
.row > .column {
    padding: 8px;
}

/* Create three equal columns that floats next to each other */
.column {
    float: left;
    width: 33.33%;
    display: none; /* Hide columns by default */
}

/* Clear floats after rows */
.row:after {
    content: "";
    display: table;
    clear: both;
}

/* Content */
.content {
    background-color: white;
    padding: 10px;
}

/* The "show" class is added to the filtered elements */
.show {
    display: block;
}

Step 3) Add JavaScript:

Example

filterSelection("all") // Execute the function and show all columns
function filterSelection(c) {
  var x, i;
  x = document.getElementsByClassName("column");
  if (c == "all") c = "";
  // Add the "show" class (display:block) to the filtered elements, and remove the "show" class from the elements that are not selected
  for (i = 0; i < x.length; i++) {
    w3RemoveClass(x[i], "show");
    if (x[i].className.indexOf(c) > -1) w3AddClass(x[i], "show");
  }
}

// Show filtered elements
function w3AddClass(element, name) {
  var i, arr1, arr2;
  arr1 = element.className.split(" ");
  arr2 = name.split(" ");
  for (i = 0; i < arr2.length; i++) {
    if (arr1.indexOf(arr2[i]) == -1) {
      element.className += " " + arr2[i];
    }
  }
}

// Hide elements that are not selected
function w3RemoveClass(element, name) {
  var i, arr1, arr2;
  arr1 = element.className.split(" ");
  arr2 = name.split(" ");
  for (i = 0; i < arr2.length; i++) {
    while (arr1.indexOf(arr2[i]) > -1) {
      arr1.splice(arr1.indexOf(arr2[i]), 1);
    }
  }
  element.className = arr1.join(" ");
}
