Name text background.... Options

[OujiBejita]

I used this code to make a background to my name :

<!-- begin code provided by createblog.com --><br /><style type="text/css"><br /><br />.nametext {color:COLORCODEgoes here;font size:30px;font-family:tempus sans ITC;font-weight:bold;background-image:url("URL goes here ");}<br /><br /></style><br /><!-- end code provided by createblog.com -->

the background works but I need the size of the space where the name goes so I can make the right sized background...and also the color of my name is staying the same color no matter what I do with it
Is there a code to hide it and make my own??
