/*
|
|
This tool is used to compare the CSS names in a chroma builtin styles with the Gitea theme CSS names.
|
|
|
|
It outputs the difference between the two sets of CSS names, eg:
|
|
|
|
```
|
|
CSS names not in builtin:
|
|
.chroma .ln
|
|
----
|
|
Builtin CSS names not in file:
|
|
.chroma .vm
|
|
```
|
|
|
|
Developers could use this tool to re-sync the CSS names in the Gitea theme.
