### Remarks

A RectTransform cannot fit a RectTransform inside a target with zero or negative dimensions. Ensure `target` has a positive width and height before calling [RectTransform.TryFitInsideCoplanarRectTransform](/engine/6000.6/script-reference/unityengine/recttransform/tryfitinsidecoplanarrecttransform.md).
