CSS3 Buttons [support thread]

[lat9]

The default (for the plugin, anyway) stylesheet_css_buttons.css contains the following towards the top:

.buttonRow a {
  text-decoration: none;
}
.button, input.button, input.cssButtonHover {
  -moz-box-shadow:inset 0px 1px 0px 0px #dbd8c0;
  -webkit-box-shadow:inset 0px 1px 0px 0px #dbd8c0;
  box-shadow:inset 0px 1px 0px 0px #dbd8c0;
  -moz-border-radius:6px;
  -webkit-border-radius:6px;
  border-radius:6px;
  display:inline-block;
  font-family:Verdana;
  font-size:13px;
  font-weight:bold;
  margin: 0;
  padding:3px 8px;
  text-decoration:none;
}

I'd need to create an account and make a purchase to be sure, but I'm guessing that you could just code:

.button, input.button, input.cssButtonHover {
  text-decoration:none;
}

to remove the underline attribute from all the buttons (normal and hover). If that doesn't work, you could PM me some test account credentials.
