By viewing the code in your web browser or by using FireBug that is explained in the JavaScript subforum, you should be able to view the (X)HT(ML), markup, the CSS styling and the JavaScript code. We highly recommend using FireBug or similar tools to viwe the code. Note that there is a Friebug Lite plugin for other browsers. The PHP code examples do not always function because of configuring etc. The same with some examples where you need access key's etc. If you find some examples that you should like to study further, I recommend that you buy the book with the code. Some SitePoint books are available in PDF format and as such available for immediately download with the attached code. You find most of what you need for your web development here. We highly recommend that you start at http://www.digitalstart.net/ if you are developing a new site or will make your site more secure. Study the security layer in detail before you start. Then the agenda should be:
- The security layer.
- The content layer. Semantic markup.
- Styling and presentation.
- Behavior.
