How to customise the Subscribe module

Hi Just hoping someone can point me in the right direction. I want to change the input button to an image only and the input text area on the sign-up module. I cant see where I can create css for input buttons because the ID has numbers appended each time you reload the page. I know I am probably missing something simple, so thanks in Advance for any help in pointing me in the right direction.

All right I have managed to re style the form after looking at other forum posts, but is there a way to completely remove the text on the subscribe button? I replaced it with an icon as per a previous post but I cant seem to remove the input text completely?

Hi frenchy74,

To remove the text you can use the css setting: text-indent: -5000px;

Kind regards,
Pete
