Pixel positioning usually anchors to a specific side. Like you can anchor label to the right side and it'll move as expected. And you also need to specify minimum width/height to keep thing sane.

Although it works poorly with translations, so it's probably not the best approach, but certainly one of the simplest. If you don't need translations, it works surprisingly well. Basically all Delphi applications used it and there were used a lot in private companies.
