I upgraded CMC from 1.4 to 2.0.0 . Under 1.4 I had the form displaying correctly horizontally but under 2.0.0 I can not get the subscribe button to align with the input boxes.
I added:

#rt-utility .cmc-signup div {
float: left;
margin-right: 5px;
}

To my template-custom.less file to get the input boxes aligned but have been unable to get the subscribe button in line. I am learning css to the best of my ability.
I would greatly appreciate your suggestions.
