Thanks for opening this! 👍 Are those style changes necessary? They seem to work as is?

Because the "jsx" syntax is used, it must be corrected, otherwise in "start" mode, the browser console will report an error, although the page can be displayed normally.

The same is true for static resources. If it is not fixed, in "start" mode, other languages than the default language will not display pictures normally. The specific reasons can be found here

Preparations have been made, after which the document translation will be taken over by "Crowdin".
