"Rate Module" How to put the number inside the button? http://drupal.org/project/rate

As you can see, the "yes/no" widget on the bottom of the screenshot is:

[button] [number]

The number is not part of the button.  How to make it like this instead:

[button number]

edit: a perfect example, the thumbs-up/thumbs-down rating widget on Yahoo Answers: http://answers.yahoo.com/question/index;_ylt=Ao37OQz9iO3ZJvacOl9pH8_j1KIX;_ylv=3?qid=20121104010935AAs5NQk

The number is in the button.  Clicking anywhere on that button registers a vote.
This is done by using some CSS. 

look at the HTML structure there. 'LI' tag is used there. Just use the anchor style to LI tag. 

background: #EEE;
border: 1px solid #CCC;
margin-right: 3px;

Use this style to li and remove anchor border. Also change the hover style of anchor tag.

Use firebug to find the structure.
