You'd need to just add a padding to the title. Please see the below CSS. You'll need to use either/or depending on if you're displaying with tables or with divs.
Tables:
Code:
#registrationTable .titleCell {
padding-right: 20px;
}
Adjust the padding as necessary to fit your needs. This is still limited to the space provided by your templates content pane.
Divs:
Code:
form.cb_form .cb_form_line label,
.cb_tab_content .cb_form_line label {
width: 28% !important;
}
form.cb_form .cb_form_line .cb_field,
.cb_tab_content .cb_form_line .cb_field {
width: 70% !important;
}
Adjust the widths as necessary. Please note without the !important tag you won't be overriding the CSS and would need to edit the templates CSS file directly to change the widths.
