Want to keep menu always appear on the top, even if you scroll down the page ?

Just follow simple two steps process.

The dynamic template gives you a great deal of control over the presentation of your site without requiring you to use multiple templates. The styles included in Twitter Bootstrap can be used as-is or overridden for custom presentation. However, the custom styling is often limited to the template itself leaving modules and components that retain the look and feel of the default Joomla experience. Joomla, however, provides a feature known as template overrides that let you customize all of the modules and components included with Joomla (and many third-party extensions) to match your template exactly.

Whenever you are using Joomla! to construct a large page that will have many visitors, it can become important to keep the page loading time as short as possible. In the Beez template, I integrate several CSS files: one for positioning, one for the distances, one for the colors, and one for the different Internet Explorer versions. These files make it easier for designers to handle and understand. But for each file, you need to send a request to the servers, which affects the performance.
