All solutions

I need help with the media queries, because if I see it on my laptop, it looks correct and works fine, but if I change min to max on mobile or desktop, everything is crashed. Exactly here:

  <link rel="stylesheet" type="text/css" href="./mobile.css" media="screen and (max-width:375px)"/>
  <link rel="stylesheet" type="text/css" href="./desktop.css" media="screen and (min-width:1440px)"/>

this is my first project of frontendmentor.

my dificult are flexbox aligns
