Tell us what’s happening:
I am using a section and a div box-container with the instructions we followed in the content “CSS flexbox” for two boxes but the boxes never show up.
Thank you for your help. I put the lines before the media query and they showed up. Then I saw that there was a “}” missing to close the media query, that was the reason it was nested. I corrected that and returned the lines to the initial place and it worked!. Than you again.
