User search app built by ReactJS and Tailwind CSS

This is my first time to use Tailwind CSS. There are some points that I feel inconvenient in development process:

• When class name attribute become longer and longer, it is hard to efficiently find the class which will be modified.

• For dark mode or responsive design, it can't collect whole classes together. Every class belong to these situation have to add "dark:", "md:" , or something before it.

• It become a little inflexible when I apply css grid by utility classes, compared with traditional CSS.

Maybe these inconvenience are because of my lack of experience, I still have a lot to learn.
