Social Proof #3

3rd attempt at this challenge. I tried a different way of positioning everything in the media queries but still gave me a little but of a hard time.

IMPORTANT QUESTION

Can someone please let me know if I am writing my html weird/wrong or am I just not using the right css in some of my code. If someone can answer this that would help a lot. I'm trying to get better at media queries, Also if someone can tell me a easier way to position things such as the 3 customer reviews, so the selfie picture and the quotes please let me know what's the best way to position things like that because that is what I struggle on the most I believe once I figure that out my projects won't take me all day.
