For task 2 from the "Test your skills: Flexbox" assignment would I need to stretch the containers using basic flexbox or tinkering with the box model?

I’m clueless on how to approach this lesson, I gave up after trying to stretch using align-self/items and also tried flex-grow

Hi @n8everest and welcome to the community :wave:

That’s a tricky one, but can be achieve with a single value for flex. This is a shorthand for flex-grow flex-shrink and flex-basis.
The important things are the values for flex-basis and flex-grow. No individual values for the third box are needed.
I hope this gets you further. Ask if you need more help. :slightly_smiling_face:

Have a nice day,
