Rails 3.1 simple_form提交样式css

Question

你好有人知道如何为一个simple_form提交按钮添加一个类,用于css style.Here是我尝试做的:

<%= simple_form_for(@drink) do |f| %>
 <%= f.submit "Add drink",:input_html =>{:class => "create"} %>
<%end%>

drinks.css.scss

.create {
    background-color:#2fd62f;
    -moz-border-radius:4px;
    -webkit-border-radius:4px;
    border-radius:4px;
    border:1px solid #dcdcdc;
    display:inline-block;
    color:#fafafa;
    font-family:arial;
    font-size:12px;
    font-weight:bold;
    padding:7px 24px;
    text-decoration:none;
    text-shadow:0px 0px 0px #70706f;
}.create:hover {
    background-color:#2fbf0f;
