Intro section with dropdown navigation

Coding this challenge was a lot of fun. Dropdown menus are an excellent way to show more content without cluttering your navigation bar. I still need to work on smoother animations and the active states when you click on the dropdown menus. I tried using CSS only, but I think it would have worked better with javascript, something to consider for future projects.

I'm not sure if using the image as background was the best solution for this challenge, even though the image is not content and it makes more sense as a background. The dimensions were a little off (by a tiny bit) and it was a little complicated to adjust it.

Question --> Is there a better way to resize background images or to make it more responsive? Maybe I'm missing something.

Thanks!
