 # Compatibility
 
 This theme is still being updated and optimized. I mainly use HTML, CSS, JS, TS, Vue, React, etc. for development, so although these languages and frameworks look good, other languages and frameworks may not be suitable for the theme. If you find any obvious problems, you can raise an issue, and I will resolve it as soon as possible.
