**3. Call Centering Styles.** Use ‘navbar-static-top’ OR ‘navbar-fixed-top’ depending on your needs. Center both this DIV and the DIV inside it having the class ‘navbar-inner’ as shown below. Scale your browser window to test the layout.
**4. Add Your Own Padding.**
In my case I padded the container classes because my navbar resides outside of a container DIV and all of my content resides inside containers.
You can use media queries to specify different amounts of padding for different screen widths.
