Responsive Huddle Landing Page

Hello! This is my second challenge! It is definitely getting easier! (At least for these basic pages) Using flexbox got easier but still learning how to layout things as I would like. I cannot think of a specific question but in general the code I use for my flexbox layouts are probably not the cleanest, so I would not mind if you have any feedback there. I just thought of something! The media queries, in general, I am not sure which resolutions to use. I looked up general widths for mobile devices (I know the projects are for 375px) for the max-widths and the in betweens from a 1440px(desktop) to a smaller opened window(~1100px). I didn't like how the flexbox looked in those smaller windows so I created an extra media query for my own preference. Is that right? Or is there a better way?
