Hi, I'm trying to adjust the submit button text padding, so that the text moves down a little, here:

I'm using this CSS:

.icf-optin-form input[type="submit"] {padding: 21px 20px;}

...as this adjusts the padding correctly in firebug, (padding was previously 5 and 20)...but it's having no effect. Wondering where i might be going wrong with this?

Many thanks
