CSS CSS Flexbox Layout Building a Layout with Flexbox Flexbox Columns Challenge

Need help with CSS flexbox code challenge

The challenge asks for the following -

'Set the columns to expand and display on one line when they are 300px or wider. But when the columns are narrower than 300px, the browser will redistribute the space and display them on multiple lines'

Can anyone advise where I am going wrong?

This defines the ability for a flex item to shrink if necessary.
