Make the parent div width the same as the children

I made this layout that seems to work, the only problem is that I would like that all che filled div are centered.

There are three possible "states":

  1. the cyan element is to the left of all the others

  2. the gold and pink elements are on two columns

  3. all elements are on a single column.

What I want: state1 state2 state3

In the first case, everything is centered and it works, in the other two it doesn't: the elements are always aligned to the left.

To center I was thinking of using margin: 0 auto but it seems the divs are bigger than their content even if I used inline-flex (look at the grey area during state #3 in the running example). Why?

How can I solve?

.container {
  outline: 1px solid black;
  max-width: 490px;
  margin: 0 auto;
}
.columns {
  outline: 1px solid black;
  display: inline-flex;
  flex-wrap: wrap;
}
.map {
  background-color: cyan;
  width: 150px;
  min-width: 150px;
  height: 150px;
  min-height: 150px;
  margin-right: 20px;
}
.content {
  outline: 1px solid black;
  background-color: lightgray;
  max-width: 320px;
}

.cards {
  outline: 1px solid black;
  display: inline-flex;
  flex-wrap: wrap;
}
.card {
  background-color: pink;
  outline: 1px solid black;
  width: 150px;
  height: 70px;
  display: inline-block;
}
.card.left {
  margin-right: 20px;
}

.texts {
  outline: 1px solid black;
  display: inline-flex;
  flex-wrap: wrap;
}
.text {
  background-color: gold;
  outline: 1px solid black;
  width: 150px;
  height: 200px;
  display: inline-block;
}
.text.left {
  margin-right: 20px;
}
<div class="container">
  <div class="columns">
    <div class="map"></div>
    <div class="content">
      <div class="cards">
        <div class="card left">card #1</div>
        <div class="card">card #2</div>
        <div class="card left">card #3</div>
        <div class="card">card #4</div>
      </div>
      
      <div class="texts">
        <div class="text left">text #1</div>
        <div class="text">text #2</div>
      </div>
    </div>
  </div>
</div>

Solution

  • use media queries in the proper way and here you go, to play with it find this fiddle link, try to resize the result window.

    .container {

  width: 150px;
  min-width: 150px;
  height: 150px;
  min-height: 150px;

  max-width: 320px;
}

.cards {

  .map {margin-right: 0;}
 
  .content {
        max-width: min-content;
