Accessible Space Tourism site built with grid & flexbox

This project was much more difficult than I thought it would be when I started, and took a lot longer than expected. This isn't a complaint, I learned a lot through building this website, and overall I'm happy with my work. At the same time, I know my website is far from perfect, especially when it comes with the spacing of my layout for each page. My destination page is much more compact than the rest of my pages, and on my technology page, the image is supposed to take up the full view width on mobile and tablet and stick to the right side on desktops. I spent a lot of time trying to fix these issues, but I haven't been able to and I feel like I got lost in my own code. Any advice on how to work through these issues would be appreciated.
