[Resolved] HowTo dispose Textfield and Submit button on the same line?

Hello,

I spent so many hours playing with additional JS file and CSS file in order to get:
- input type=text (width ~70%) and input type=submit (width ~30%) on the same line

but I've FAILED !

I just want something disposed like the "search jQuery" input of this page (top-right).

So, does anyone know a pretty simple way to do it ?
