Html og C#

Hej

Har lidt problemer med at styre det html som C# genererer. Muligvis kan det klares på en anden måde, end jeg gerne vil.
Jeg laver en lille meningsmåling, hvor jeg dynamisk skal generere
textfelter. Til det formål har jeg benyttet en placeholder og det virker umiddelbart, men jeg vil gerne kunne indsætte et linjeskift efter hvert textfelt i min html. Hvordan gør man det ?

Koden ses herunder, som består af to sider, hvor side1 redirecter til side2 og side2 viser så
