In Spanish, ‘you too’ can be translated as ‘tú también’ when speaking informally or ‘usted también’ when speaking formally.
For example, if someone says ‘Have a good day!’ (‘¡Que tengas un buen día!’), you can respond with ‘Tú también’ or ‘Usted también,’ depending on the level of formality. This phrase is commonly used to reciprocate a sentiment or wish that someone has expressed to you.
