What is the initial process and how do you get your hands on WordPress in order to create your own website templates? You will need to go to WordPress.org and download a version in the language of your choice. You then extract the zip folder into the root of your site, and you will see tons of files pop up. Don't worry about opening those or going into them as what you need to work with will be significantly small. Then go to yoursite.com/wp_admin/ and you will go through the simple installation process which is basically just WordPress hooking itself up to a database which it creates in your server in order to work. That's all there is then you can start rolling.
The centre part of any business web template has to be kept for showing off products or services. In the centre if there is a place the products or service with little description the users can easily understand what type of business you are running or what they can get from your site. So it is necessary that the layouts give you scope to utilize the space for attracting your visitors cum customers.
