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.

Redlines: We don't include redline comps because it's always more accurate to use developer tools to inspect the coded components, or a plugin such as the Prism Redline Tool.

Usage

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.

Do's and Don'ts

Common Button Labels and Usage

Title case, 2-3 words maximum.
Do not combine actions in a label (exception: "Customize & Buy").
If standard labels don't fit the button's purpose, align label with the task the user is attempting.

Accessibility

The W3C Web Accessibility Initiative (WAI) develops standards and support materials to help you understand and implement accessibility.

An off canvas is highly similar to a modal.

Please follow the best practices for modal dialogs from WAI-ARIA authoring practices 1.1.
