Thank you for the reply!
Yes, I do that method but if I make a shape then add texts, then each time I need to adjust width the shape depends on the text length.
>>For its height you can either use a paragraph decoration (> Paragraph Panel) or its text frame height with a fill colour.
That works when the paragraph is just one row, but my situation I have multiple like the screenshot ("fill colour" apply all of back ground of the frame text).
I need to edit each lines (highlight).
>>... or simply switch to a Text Tool, click + and start typing.
And this method, the shape doesn't change the size depends on texts.
The first video of Canva, background of texts are following the texts. That is very helpful for my work.
Seems like, no way to edit size of highlight,,,?
