Off Canvas

Used to present secondary content or navigation which could be a part of the page but due to limited screen real-estate, or to focus user attention, sits just outside screen until triggered by the user.

An off canvas is a modal drawer that slides in from the right.

The page behind becomes frozen while an off canvas is open.

The browser scroll bar (or facsimile) controls the off canvas content while it's open instead of the page behind.

On larger breakpoints, an off canvas takes over a maximum of 10/12 columns, leaving a portion of the main screen visible.

On smaller breakpoints, the off canvas takes over the entire screen.

  • On smaller breakpoints, tabs become a vertical CTA list that each opens its own off-canvas.

You can override the default width of an off canvas by applying one of the following classes to dds__modal-offcanvas:

  • dds__modal-width-25
  • dds__modal-width-50
  • dds__modal-width-75
  • dds__modal-width-100

The off canvas masthead is a fixed element that remains in its persistent location as the user scrolls.

To close an off canvas, either select the left-most CTA in its masthead (typically "< Back") or on a touchscreen swipe it to the right.
