Hi I’m going to help you a bit but not for the whole template.
I’ll point you in the right direction but you need to get this done yourself
our support scope is for the extension itself.
You need to study about CSS more
This is a good resource.
CSS Tutorial
You have not added the layers to the right place there still in the
Index.php you needed to cut and paste them to the style sheet.
You also have two style body calls the style which I have fixed for you and added the layers to the right location in the style sheet.
You need to remove the layers code from your index.php page.
You are also going to have edit your style sheet so all of your colors match.
I would suggest two things.
1. Read up on CSS at w3schools.com
2. Use this editor for your CSS called Top Style
TopStyle for Windows - HTML, xHTML and CSS Editing in a Single Program
it will help you a lot and they have a trial version.
See the CSS attachment in the post and download it and replace the one you have in your system.
Cheers,
Brian
