Example
The following HTML page illustrates a simple Hello World page using Bootstrap 3.
The page contains a full-width navigation bar with example links and a drop-down control. The navigation bar takes advantage of Bootstrap's mobile first capabilities. It starts collapsed in mobile views and become horizontal as the available viewport width increases.
In addition, a jumbotron element has been used to display featured information.
