研究方向
The issue asks whether MUI should replace px with rem for better mobile friendliness. Review the discussion in comments for pros and cons. Examine current CSS files for use of px units and identify which ones are critical for responsiveness. Propose a pull request that converts appropriate px values to rem, considering common font sizes and breakpoints. Seek maintainer input on the preferred base font size.
