Is it possible to style up an <input type="submit"> in a form with no classes or ids?

Question

I'm trying to style up a form within the Wishlist Member plugin in Wordpress and there isn't a template where I can physically go into and add classes, id's, etc. So I was wondering if there was a way to style up an <input type="submit"> with no class or id without affecting the <input type="text"> fields using javascript maybe. Thanks.

Answer 1

This should do the trick

input[type=submit] {
    yourCss
}

Answer 2

You can add style with CSS even if there is no class/id. The following selects all input elements with attribute type="submit":

input[type="submit"]{
   /* style */
}

The above is very generic, it's better to be more exclusiver. So include some of its parents , preferable those with an ID/class:

div#someID form input[type="submit"]{
   /* style */
}

(assuming a parent <div id="someID">)
