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