How can I have two fixed width columns with one flexible column in the center?

I'm trying to set up a flexbox layout with three columns where the left and right columns have a fixed width, and the center column flexes to fill the available space.

Despite setting up dimensions for the columns, they still seem to shrink as the window shrinks.

Anyone know how to accomplish this?

An additional thing I will need to do is hide the right column based on user interaction, in which case the left column would still keep its fixed width, but the center column would fill the rest of the space.

Here's a JSFiddle: http://jsfiddle.net/zDd2g/185/

Instead of using width (which is a suggestion when using flexbox), you could use flex: 0 0 230px; which means:

  • 0 = don't grow (shorthand for flex-grow)
  • 0 = don't shrink (shorthand for flex-shrink)
  • 230px = start at 230px (shorthand for flex-basis)

which means: always be 230px.

See fiddle, thanks @TylerH

Oh, and you don't need the justify-content and align-items here.

img {
    max-width: 100%;
}
#container {
    display: flex;
    x-justify-content: space-around;
    x-align-items: stretch;
    max-width: 1200px;
}
.column.left {
    width: 230px;
    flex: 0 0 230px;
}
.column.right {
    width: 230px;
    flex: 0 0 230px;
    border-left: 1px solid #eee;
}
.column.center {
    border-left: 1px solid #eee;
}
