I have the same question. I put in this code:
#cntctfrm_contact_form label {
float:none;
}
… which I found here: http://wordpress.org/support/topic/plugin-contact-form-centering-form-on-page?replies=13
… but it doesn’t work. For the record, I’m using the TwentyTwelve theme, and I put that code into my child theme (which has other modifications that work just fine).
Hello,
The css, which you should add, depends on theme.
For example, you should add these lines to the css file of TwentyTwelve theme:
#cntctfrm_contact_form {
margin: 0 auto;
width: 350px;
}
Kind regards,
