Question

I have a wrapper div and many content blocks. The content block can be of any number.

<div class="wrapper">
  <div class="content-block">Something goes here</div>
  <div class="content-block">Something goes here</div>
                             .
                             .
                             .
  <div class="content-block">Something goes here</div>
</div>

I wish to form a pyramid structure using these content-blocks as it appears below:

Is it possible to achieve pyramid like this? The above image is just an example, there can be more than 10 content-blocks or even less.

Check out this very simple JavaScript/CSS solution:

var objContainer = document.getElementById("container"),
  intLevels = 10,
  strBlocksHTML = '';

// Using innerHTML is faster than DOM appendChild
for (var i = 0; i < intLevels; i++) {
  for (var n = 0; n < i + 1; n++) {
    strBlocksHTML += '<div class="buildingBlock"></div>';
  }
  strBlocksHTML += '<div></div>'; // Line break after each row
}

objContainer.innerHTML = strBlocksHTML;

.buildingBlock {
  display: inline-block;
  width: 20px;
  height: 20px;
  margin: 2px 5px;
  background-color: #eee;
  border: 2px solid #ccc;
}

#container {
  text-align: center;
}

<div id="container"></div>
