You have several possibilities:
- Stick to simple theme and use <s:fieldError > to display validation 
errors. Not recommended as you cannot use some nice features of struts2

- Take another theme that is shipped with struts2 (or a plugin like 
jquery- or bootstrap-plugin), see how the generated html looks like and 
write your own css rules for that html

- Write your own theme

- Add <s:head /> to your html header, that includes css and js files 
required by struts2
