Change Subscribe button colors

I have used custom CSS to successfully change the button font and background color in the sidebar widget for my website:

/* MailPoet Subscribe submit button */
.widget input.wysija-submit {
background: #3e720d;
border: 1px solid #ccc;
color: #ffffff;
}

However this is not working at the bottom of my blog post where I have used [wysija_form id=”1″] to add the subscribe form. Why does the CSS code not work and what do I need to do to change the colors?
