I am not going to explain how to setup your WordPress, or how easy it is, because most hosting companies are going to offer you a setup WordPress hosting package and after choosing your domain name, you will obtain a user name and password and be able to login.
For my example site I am using a local web server on my network that can not be accessed from the Web. So dont worry about the wierd domain names I am using.
I will be using the NetBeans IDE editor when showing you the code behind the theme design. You could use the same if you are goign to get adventerous, you will find it here to install but it is not needed.
What is in a child theme and Installing the child theme on your WordPress Site. – Yes I have one ready for you and you can download it here
How we can edit the theme with netbeans. – here is how to make it the default editor.
If you want, you can edit the style sheet with the editor in the theme dashboard. If the editor is not avilable to you then you may need to have a change made to your wp-config.php file.
However, there is no error checking, so be careful.
