Flexbox

Hi all , Could I get any feedback on my solution ? I completely failed on this one I wasn't able to deal the space of the headings and paragraphs for responsive and couldn't find how to made the background like the design.

I posted anyway because I think this is good thing to see that sucess is not always shiny.

If someone have some ressources to learn more efficiently background property or prevent paragraph and heading to wrap I'm open.

I'm moving on the next challenge and coming back on this one later

Thanks for reading !
