WordPress is an open source and free content management system based on PHP and combined with a MySQL or Oracle database. It can be used to power any website. Features include a powerful template engine, known as Themes, and a highly efficient plugin architecture. Unlike HTML editors, WordPress allows a site owner to create a custom design that is then displayed on the front end of every web page.
There are many themes available for wordpress. These themes can be added to increase the look and functionality of your site. They also allow you to change existing plugins and add/remove other plugins as necessary without having to figure out how to configure anything. One of the best features of wordpress is that it integrates tightly with other open source software like Joomla and Drupal, and thousands of third party plugins exist for wordpress.
While this all sounds very complicated, it really just involves installing a web server, reading a few configuration files, and then creating a customized WordPress template. All of this happens without ever needing to know any HTML or CSS code. A content management system is used in conjunction with WordPress so that changes to the site can be applied by users without needing to know anything about the inner workings of the CMS. There are literally thousands of plugins available for wordpress that can help customize your site and make it do nearly anything you want. In order to take full advantage of the capabilities of wordpress, you will need to learn how to install plugins. Luckily there are many tutorials available online that walk through the entire process step by step.
