As blogging evolves, as more and more Internet users embrace this revolutionary publishing medium, the need for customization increases proportionately. Every new version of WordPress comes out with new features that help you customize your blog. But when it comes to blogging, what exactly customization mean?
Customizing a WordPress blog can range from designing your own theme to adding new publishing features, displaying featured blog posts, manipulating sidbar widgets and components, designing and displaying unique navigation, creating member-only pages and creating custom login features.
Since WordPress is entirely written in PHP you can incorporate even advanced features if you know a little bit of the web programming language. In most of the cases you don’t even need plugins. Simply add some lines at the appropriate places and you’ve got yourself a new custom feature for your WordPress blog. This blog post mentions many such code examples.
