Design #28

Allow for quick navigation through the history

Browsers allow users to quickly navigate between pages in their history (Back and Forward buttons). This features avoids the need to request and download the page from the server for a second time. This prevents consuming unnecessary bandwidth and generating additional HTTP requests.
It is therefore recommended to not implement elements that render the page unoperational after leaving it.

Development #9

Split CSS

Use a group of CSS elements instead of only one, and only call CSS that is useful for the situation. Doing so minimizes the size of the page when it is first loaded, thus saving bandwidth and reducing CPU load.
