Fluid flexbox grid with fixed column widths

Question

I have a container set up via flexbox. I'd like to equally distribute each of the tiles inside the container but keep them at a fixed width of 220px.

I've come close using flex-grow and setting a min-width: 220px, but it obviously has computationally resized the tiles in order to fill the container.

I've also set up some media queries so that the tiles stack on certain breakpoints.

With my current styling is it possible to keep these tiles at 220px without them stretching? Can this be done via flexbox? Is there an alternative that's just as good as flexbox?

.container {
  border: 1px solid red;
  display: flex;
  flex-wrap: wrap;
  margin: 0 auto;
  max-width: 2000px;
}
.tiles {
  border: 1px solid black;
  margin: 0 15px 30px 15px;
  flex-grow: 1;
  padding: 0;
  height: 220px;
  min-width: 220px;
}
@media screen and (max-width: 1140px) {
  .container {
    max-width: 850px;
  }
}
@media screen and (max-width: 2040px) {
  .container {
    max-width: 1750px;
  }
}
@media screen and (max-width: 1790px) {
  .container {
    max-width: 1500px;
  }
}
@media screen and (max-width: 1540px) {
  .container {
    max-width: 1250px;
  }
}
@media screen and (max-width: 1290px) {
  .container {
    max-width: 1000px;
  }
}
@media screen and (max-width: 1040px) {
  .container {
    max-width: 750px;
  }
}
@media screen and (max-width: 790px) {
  .container {
    max-width: 500px;
  }
}

<div class="container">
  <div class="tiles"></div>
  <div class="tiles"></div>
  <div class="tiles"></div>

I'd like to equally distribute each of the tiles inside the container but keep them at a fixed width of 220px.

Can this be done via flexbox?

Yes, and yes.

Instead of using flex-grow and min-width on the tiles, use the flex property.

So, instead of:

.tiles {
    flex-grow: 1;
    min-width: 220px;
}

Try this:

.tiles {
    flex: 0 0 220px; /* don't grow, don't shrink, stay at 220px width */
}

The flex property is shorthand for flex-grow, flex-shrink, flex-basis.

The flex-grow property controls how a flex item will grow relative to other flex items in the container when extra space is distributed. By setting the value to 0, it doesn't grow at all from the initial main size (defined by flex-basis).

The flex-shrink property controls how a flex item will shrink relative to other flex items when they overflow the container. By setting the value to 0, it doesn't shrink at all from the initial main size (defined by flex-basis).

The flex-basis property sets the initial main size of a flex item.

I've also setup some media queries so that the tiles stack on certain breakpoints.

By using the flex property, as specified above, along with flex-wrap, which you already have in your code, you may not need media queries. Consider scrapping them.

At this point, you may have your layout: DEMO

OR

You may be at a common sticking point: When flex items wrap, the container does not recalculate its width to shrink-wrap the fewer columns, resulting in a large area of whitespace on the right.

UPDATE

After a few clarifications and revisions were made in the comments, the solution was found:

HTML

<ul id="content">
    <li class="box"></li>
    <li class="box"></li>
    <li class="box"></li>
            ...
            ...
            ...
</ul>

CSS

*
{
    margin:0;padding:0;
}

#content {
    display: flex;
    flex-wrap: wrap;
    list-style: none;
    margin:0 auto;
}
.box {
    flex: 0 0 90px;
    height: 90px;
    margin: 5px;
    background-color: blue;
}

@media (min-width: 200px) {
  #content {
    width: 200px;
  }
}
@media (min-width: 300px) {
  #content {
    width: 300px;
  }
}
@media (min-width: 400px) {
  #content {
    width: 400px;
  }
}
@media (min-width: 500px) {
  #content {
    width: 500px;
  }
}
@media (min-width: 600px) {
  #content {
    width: 600px;
  }
}
@media (min-width: 700px) {
  #content {
    width: 700px;
  }
}
@media (min-width: 800px) {
  #content {
    width: 800px;
  }
}
@media (min-width: 900px) {
  #content {
    width: 900px;
  }
}
@media (min-width: 1000px) {
  #content {
    width: 1000px;
  }
}
@media (min-width: 1100px) {
  #content {

  }
}

So flexbox has the ability to grow and shrink, which you can turn off (you can read a little more about that here, I find this a nice, quick flexbox guide). Shorthand for defining flex-grow, flex-shrink, and flex-basis all at once is flex: 0 0 auto, the zeros meaning that the box won't grow or shrink, but remain the same size you defined previously. I modified your jsfiddle to show how it works:
