[SOLVED] CB Login in one line

Hi
I would like to have the CB Login in one line (Mail+password for exemple in only one line).
I try the bootstap horizontal and default horizontal...no change.

With CSS i can change size, text, color, background.... but not the placement.

I dont want to change the file /www/modules/mod_cblogin/tmpl/bootstrap-horizontal.php for example, because in case of upgrade, my file is crushed.

Is there a solution ?

Thank you

I answer to myself :

with the use of
float:left;
in the css, i correct my problem.
