What are you most proud of, and what would you do differently next time?

This is a rather comprehensive project which has many functionality and styles, including theme switcher, search bar, filter, and so on, I am satisfies with the output, it requires some skills and efforts to do it and realize the effect. Until now, it looks I have finished all the free chalenges, it's somthing I would feel acccomplishment and thanks for providing the projects.

What challenges did you encounter, and how did you overcome them?

The native form element, and have limited stylings you can do, like you can set the color but not height or other styles, I tried various methods to make it as close to design, finally I using other tag to make it work, it has great result.
