text paragraph color background with rounded corner

[d-zimin]

Hello.
I need a black text where each paragraph in it has white background with rounded corner. Is there a way to do it?

You can add separate text boxes in a rectangle?
What's your use case, that may help to understand the request.
Will the text boxes change size?

Hopki, text box has stretch size in percent and it has variable content via $(hd) as well.
