lounge 플랙스-스페이스비트윈등이 않되요~

안녕하세요? 쌤, 아직은 초보라 질문이 좀 있습니다~

1. .lounge_cont에 flex justufy-content: space-between으로 이미지와 컨텐트의 간격을 벌려주셨는데 제것은 많이 떨어져있지 않았고, 또 첫번째 이미지가 600px도 아니여서인지 .lounge_txt_wrap의 넓이를 calc(100%-650px)를 주면 글자가 길게 아래로 떨어지길래 이미지를 600px을주고 calc를 (100%-500px)으로줄여서 했어요, 그런데도 이미지와 텍스트 간격이 붙어있어서 굳이 padding-left:50px을 줬습니다.

그랬더니 flex- order:2를 주고 순서가 바뀐 두번째 lou02는 이미지와 글자또 붙어버려서 굳이 이미지에 마진을 줘서 띄었더니 뭔가 좀 안맞는거 같아요.

아래 파일 css보시고 왜 제거는 똑같이 쳤는데 플랙스나 칼크가 다 안맞고 패딩과 마진으로 띄어야하는지 모르겠어요.

2. 그리고, h3를 1.875vw를 주셨는데 글자에 vw를 써본적고 em도 아직 헷갈려서..이게 몇px로 맞추신건지요? 또 html 62.5%라 em이나 %로 주면 안되나요?

3. 그리고 reset.css - body: line-height: 1.5 주셨는데 이건 1.5em이란 뜻맞나요? 이번 텍스트들의 line-height가 65px이런데 왜 그렇게 주시는건가요? 위에처럼 1.5em등으로 맞춰야하지 않나요?

4. 마지막으로 .header_wrap{ max-width: 1100px} 인데요. 맥스위드가 처음이라 그냥 위드와 무슨 차이가 있어서 주신건지 궁금합니다.

질문이 모이다보니 많아 졌네요..너무 감사드립니다. 쇼핑몰 스타일을 포폴로 만들어야하는데 도움 많이 됩니다!^_^
