Reply To: max width for simple aweber optin widget

Yes you can do that using CSS.

Use the class .twb_widget_wrapper for that.

For example, if you want to limit the width to 250px, your code will look like following:

.twb_widget_wrapper {
  width: 250px;
  margin-left: auto; /* align center from left */
  margin-right: auto; /* align center from right */
}

Should be pretty easy.
