I want the container div (#a-container in this example) to fit the width of its children, that are inline-block divs. In this example, I want the #a-container div to be just the size of 2 .a div. Is it possible? (pure CSS please)
#a-container {
  width: 250px;
  background-color: gray;
}
.a {
  background-color:blue;
  width:100px;
  height: 100px;
  display:inline-block;
}<div id="a-container">
  <div class="a"></div>
  <div class="a"></div>
  <div class="a"></div>
</div>
