How to adapt div div width to content

Question

My idea is to give an adaptive div width. When I have only one element, the width should be the same as the element in the div container.

Any suggestion on how to do this?

Example: http://codepen.io/tomasfrancisco/pen/PNvLLw

HTML:

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

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

CSS

#container {
  display: flex;
  flex-direction: row;
  flex-wrap: wrap;
  max-width: 200px;
  padding: 10px;
  margin: 20px;
  background-color: blue;
}
#container .item {
  width: 80px;
  height: 50px;
  background-color: red;
  margin: 10px;
}

Answer 1

you can use display: inline-flex

#container {
  display: inline-flex;
  flex-direction: row;
  flex-wrap: wrap;
  max-width: 200px;
  padding: 10px;
  margin: 20px;
  background-color: blue;
}
#container .item {
  width: 80px;
  height: 50px;
  background-color: red;
  margin: 10px;
}

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

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