how to change existing form

Hi I have some existing web page
I need to duplicate the page and then to change the form to this form :

<link rel="stylesheet" 
  target="_blank" rel="nofollow" href="">

 before </body> closes:
  <script src="">
</script> if jQuery is already in page, no need to add this line.
 <script src=""></script>
   $(function() {
container: '#cont',
 pipe: '0rSX2a2',
 campaign: '13',
 sub_campaign: '30DayChange',
  password_required: true,
  extra_data: {
   subAffiliateId: "30DayChange"

and to put this div instead of the original form:

  <div id=“cont”></div>

I don’t understand what does it mean to change the existing from to this form:

<link rel=”stylesheet”
target=”_blank” rel=”nofollow” href=””>
this is an css file, any one can please explain me what does it mean?

Your question isn’t very clear, but i think i got it.
There’s a CSS rule called “cascade”, wich means that more specific styles overrite the generic ones, so, you can specify a style to your <div> element by adding

        style propeperties


        style propeperties
