Principles tutorials

We have decided that we need to have different foundational tutorials that can be referenced from the practical tutorials. Possible topics:

  • Document outline
  • Keyboard navigation

Keyboard navigation brainstorm

  • Mouseless
  • Traps?
  • Conventions
  • Focus order/precticability → meaningful sequence
  • Managing focus
  • Tabindex 0/-1
  •  :hover/:focus → visibility → Don’t remove outline!!
  • accesskeys?
  • bypass blocks of content (→ landmark roles, headings until supported)
    • We want to push landmark roles. Keyboard navigation to landmarks w/o screen reader by using a Browser extension.
    • (dboudreau) - Until either landmark or headings navigation is widely and natively supported in browsers however, we need to keep promoting skip links
  • skiplinks
  • focus styling
  • mobile platform considerations with no keyboard?

Practical tutorials

Basically those are very, very similar to the Images tutorials. We aim for the following structure:

  • Tutorial
    • Concepts page
    • Decision tree
    • At least 1 topic page
    • Maybe a Tips and FAQ page

Show/Hide tutorial content brainstorm

Concepts

  • only specific content is shown
  • mechanism to show and hide content
  • convey state of the widget (Ref: Discoverability tutorial)
  • Ref: Keyboard access tutorial
    • tab panel: Navigation with left/right – Content is after the list of navigation switches
    • accordeon: Navigation with tab – Content is inline between the switches

Benefits for PwD: motor, visual, cognitive

Decision tree

  • one part of content to switch on → tab panels
  • multiple parts of content → accordion
  • aria-selected → tab panels
  • aria-expanded or multiselect → accordion

Topics

1. Disclosure
  • Heading + Button CSS Example
  • JavaScript Example
2. Simple hide/show components
  • Switches: List of links. Activation of one: revealing one, hiding others. (tab panel)
  • Switches: Headings. Activation of one: revealing one, hiding others. (accordion)
3. Complex hide/show components
  • Switches: Headings. Activation of one: revealing one, not hiding the others. (accordion)
(others)
  • Hide things to visual users, hide from screen readers and vice-versa (route as an alternative text for a google map)
  • offscreen
  • aria-hidden

Modal dialog tutorial brainstorm

  • Pretty severe screen reader problems: Switching to forms mode in modals. Possible solution: nest a
    inside the
  • Esc-Key -> Close

Consideration Page

For tutorials we can’t cover in full, we want to have a page with simple considerations when using components. Example for Carousels:

Carousels/Sliders

  • Animations should be stoppable
  • Switching from one panel to another must be possible with the keyboard
  • Tabbing should not advance the carousel but skip invisible panels
  • If the focus is in a panel, don’t advance to the next panel
  • If the mouse is hovered over a panel, don’t advance to the next panel

Notes

  • Tables Tutorial: Calendar table (headers/id, to use in the Form: Datepicker)
  • Tables Tutorial: Splitting complex table into multiple tables
  • Tab panels have to be visually distinctive
  • Table tutorial has to be more conceptual
  • Forms Tutorial: Change of Context
