is the grammar of には and では

How to use には and では in the sentence
`～ + に + なる` is a basic set phrase that means "to go ～", "to become ～", "to
end up with ～", "to turn out to be ～", etc. This に is roughly an equivalent of
English "to".

  * 大学生になる to become a university student
  * 終わりになる to come to an end
  * 元気になる to fee/get better, to recover

こと on its own refers to an event. Here, そんなこと refers to the resulting burnt
skin, so it can be translated as "such a result/appearance". そんなこと is marked
with に. は after に is a [topic/contrast marker used in a negative
clause](https://japanese.stackexchange.com/q/1077/5010).

Therefore:

> 日焼け止めを塗っていれば、  
>  If you had put sunscreen on,
>
> そんなことにはならなかっただろうに。  
>  (I suppose) You wouldn't have ended up with such an appearance.
