Responsive Design

Responsive web design (RWD) is an approach to web design that makes web pages render well on a variety of devices and window or screen sizes. Recent work also considers the viewer proximity as part of the viewing context as an extension for RWD. Content, design and performance are necessary across all devices to ensure usability and satisfaction.

Characteristics

A site designed with RWD adapts the layout to the viewing environment by using fluid, proportion-based grids, flexible images, and CSS3 media queries, an extension of the @media rule, in the following ways:

• The fluid grid concept calls for page element sizing to be in relative units like percentages, rather than absolute units like pixels or points.
• Flexible images are also sized in relative units, so as to prevent them from displaying outside their containing element.
• Media queries allow the page to use different CSS style rules based on characteristics of the device the site is being displayed on (e.g. width of the rendering surface – either browser window width or a physical display size).
• Responsive layouts automatically adjust and adapt to any device screen size, whether it is a desktop, a laptop, a tablet, or a mobile phone.

Grid System

Pages are built using the Bootstrap Grid System. It is a responsive, mobile first fluid grid that appropriately scales up to 12 columns as the device or viewport size increases.

Current Implementation

In Concur’s current Bootstrap Grid System implementation, most pages have responsiveness disabled at screen widths below 980 pixels. When the screen (or window) is reduced below that width, the page content remains 980 pixels wide and the window scrolls horizontally. We call this behavior “Partially Responsive” (vs “Fully Responsive”).

NOTE: While there is a way to enable “Fully Responsive” behavior on a page-by-page basis, most pages likely won’t work properly on small and extra small sizes as they won’t have definitions for how the columns should flow at those sizes. It would require a design exercise to define that layout.
