Responsive space website using Grid layout

Thank you Scrimba and Kevin Powell for the amazing tutorial.

Don't know what the issue with crew page is but sometimes the layout won't fit in my screen and a vertical scrollbar will appear and other times it works just fine excluding the second tab (the Mark Shuttleworth image is too big).

The technology page is not quite accurate to the design. The image, which is supposed to stick to the edge has some space in this implementation. I tried to but was overwhelmed by the overflow issues it created. If you can help me figure out the solution for this, it would be really helpful.
