The code box cannot enter anything, and there is no cursor，anyone know why？

Can you provide a demo repo or codepen etc.

Please verify if styles for code flask editor are not affected by your site styles. Unfortunately code flask editor is very error prone to such behaviour, as syntax colouring is on top of regular textarea, and everything has to be styled correctly (lack of background at upper level, font styles and alignment, etc.).
