The graphic is inserted in the run of text (inline) and then the alignment of the graphic set to suit how you want it to appear in relation to the text. Options are Top, Text Top, Super etc. etc and Left and Right.
My container uses the CSS3 corners action for its curved corners and there is some margin on the white graphic to keep the text at bay.
To get the text to do that you need to use Left or Right as the alignment setting. Anything else will give you various results, but not full run around.
I did that. But, the box I want things to run around never seems to be where I want it. Then, I add text and somehow things get messed up and I wind up with a big “X” in my box and everything is gone and I have to revert to get everything back.

Welcome the wonderful web!
The simple analogy is that a bit of paper has fixed dimensions whereas the web doesn’t. Try painting a picture onto the surface of a pond and that gives you some idea of what you can be up against.
