Problems with alignment of input and button

Hi, Sorry for my bad english. I have problems with the input field and the button. Both were shifted to the right before the update. First I inserted the following code neutral.css.

.newsletter {
height: 70px;
}

.newsletter .newsletter-submit {
border: 1px solid #ccc;
border-radius: 3px;
background-image: url(widget-neutral/button.png);
color: #fff;
float: right;
margin: 10px 0px 0px 150px;
cursor: pointer;

After the update, everything is shifted to the left (left-justified). Haunted it a permanent solution?

Thanks for your answers
