maybe some bugs about app.container、app.success、app.text

[yuezZYMSQTD]

I'm learning the blog example. Maybe I met some bugs about the widgets:
1、When using app.container(border=True), the page doesn't show the border.
2、When using app.success(f"Hello, username"), the page only shows raw text: Hello, username. However the purpose is to show bold text.
3、I wrote some contents in the text area with the enter key on computer keyboard. But when using app.text(post['content']) or app.markdown(post['content']) or app.write(post['content']), the page dosen't show the line breaks such as print("123\n456") in python console. Contents are shown only in one line.

Hi! Thank you so much for trying out the blog example and taking the time to report these issues. Since Violit is still in its early stages, detailed feedback like this is incredibly valuable to me!

You are completely right, and these are indeed bugs. Here is my plan to address them:

• app.container(border=True): This is a missing CSS binding issue. I will fix the component so the border is properly rendered when the argument is True.

• app.success(): It should definitely render with proper styling (colors/bold text) rather than just raw text. I'll make sure the correct UI component is applied.

• Line breaks (\n) in app.text/markdown/write: This happens because standard HTML ignores raw \n characters. As a quick temporary workaround, you can replace \n with
  in your string before passing it to app.markdown(). However, I will update the internal logic so that app.text and app.write automatically handle line breaks correctly (e.g., using white-space: pre-wrap).

I will work on these fixes right away and include them in the next patch update. I'll notify you in this thread once it's merged and released. Thanks again for your great contribution!
