space between divs – display table-cell

You can use border-spacing property:

HTML:

<div class="table">
    <div class="row">
        <div class="cell">Cell 1</div>
        <div class="cell">Cell 2</div>
    </div>
</div>

CSS:

.table {
  display: table;
  border-collapse: separate;
  border-spacing: 10px;
}

.row { display:table-row; }

.cell {
  display:table-cell;
  padding:5px;
  background-color: gold;
}

Any other option?

Well, not really.

Why?

• margin property is not applicable to display: table-cell elements.
• padding property doesn’t create space between edges of the cells.
• float property destroys the expected behavior of table-cell elements which are able to be as tall as their parent element.
