Question

EDIT

I want to achieve something like that:

                     Title title title title title title 
                                ------------
                                |input text| some text
                                ------------

               Title title title title title title title title
                                ------------
                                |input text| some other text
                                ------------

                           Title title title title
                                ------------
                                |input text| some other other text
                                ------------

what is the easiest way to have have it centered, but not like this:

                     Title title title title title title 
                                ------------
                                |input text| some text
                                ------------

               Title title title title title title title title
                             ------------
                             |input text| some other text
                             ------------

                           Title title title title
                          ------------
                          |input text| some other other text
                          ------------
