Hey Steven,
Yes, you can do this with css. Alternatively if you are not happy with out default html, you can create a template override for modules/mod_cmc/tmpl/default.php and simplify the structure & then style with css.

In the attachment I just changed:

.cmc-signup .control-group {

    margin-bottom: 9px;

}

to

.cmc-signup .control-group {

    margin-bottom: 9px;

    display: inline-block;

}

Regards,
Daniel
