How to position image in Harlowe 3.2.0

This make me crazy! There seems to be like hundreds different ways of positioning an image. And because I’m a total noob at this they all seem unnecessary problematic and apparently are different in some strange ways…

Could some wonderful human being just help me out and show me how to position an image in a clean and smooth CSS code in Harlowe…

I just want to know how to postion it to the left, center or right.

Yours truly
