How to?? Install optin box in a nice template??

Hi there, I want to do a 'hard' thing for me, hahaha...

I want to put my optin box which is shown like below:



and I want to embed it to a nice template, shown just like below:



You know what I mean right? I want to get rid of ugly optin box, and embed it into a nice template.

How can I do that? Let's say I'll give the optin code below, can u show me from which part to which part should I embed the code to show properly in the nice template?


Here's the full code I used to have the 'ugly' standard optin box:

<div class="o-form"><div class="o-form-header"><h2 id="o-form-title">Mail List Subscription Form</h2><p id="o-form-description">Please fill in and submit the form below to subscribe to our mailing list.</p></div><form action="http://www.imnicamail.com/v4/subscribe.php" method="post" accept-charset="UTF-8"><div class="o-form-row"><label for="FormValue_EmailAddress">Email Address</label><input name="FormValue_Fields[EmailAddress]" value="" id="FormValue_EmailAddress" type="text"></div><input name="FormButton_Subscribe" value="Subscribe" id="FormButton_Subscribe" type="submit"><input name="FormValue_ListID" value="7647" type="hidden"><input name="FormValue_Command" value="Subscriber.Add" id="FormValue_Command" type="hidden"></form><style type="text/css" media="screen">.o-form{background-color:#FFF4ED;border:1px solid #814913;}
.o-form form{margin:0px;padding:0px;}
.o-form .o-form-header{background-color:#814913;padding:9px;}
.o-form h2{color:#fff;font-family:Arial,sans-serif;font-size:18px;line-height:27px;margin:0px;padding:0px;}
.o-form p{color:#fff;font-family:Arial,sans-serif;font-size:12px;line-height:18px;margin:0px;padding:0px;}
.o-form .o-form-row{margin-top:9px;padding:0 9px;}
.o-form .o-form-row label{color:#814913;font-family:Arial,sans-serif;font-size:12px;display:block;font-weight:bold;}
.o-form input[type="text"]{border:1px solid #814913;color:#814913;padding:5px 7px;}
.o-form input[type="submit"]{margin:20px 9px 18px 9px;}</style></div>



thx in advance, I think it's a bit complicated for me. ...
