I hope I can help!
This is something that I really cannot explain how to do in a single post. I would recommend that you start reading W3Schools
. Basically, there are a number of ways you can create a website. There are many program out there than can do most of the work for you, such as Dreamweaver
(a more expensive product). You can also use pre-made layouts such as webs.com
I hope that helps!
