Custom coding

Hi,

I’m not happy with the default look/style of this widget – I’m trying to put it top right in my header.

It looks like this: http://i67.tinypic.com/2lwnmt4.png

Can you let me know where in the editor i might be able to
– remove the text “email address”
– set the it so that there is a
between “signup” and the form.

I also want to style the form. I’m trying to override the basic button like this? Is there a better way to force it to override?

#mc_signup_submit {

   background: #4CAF50;
    border: none;
    color: white;
    text-decoration: none;
}

I had to disable the mail chimp css because the code was coming up as text in my header.
