  • Known Issues:

We inspected the Horizon (Havana release) for web accessibility and found the following problems.

  • 1.1.1 Non-text Contents
    • A few non-text contents such as Network Topology (for Neutron) and Resource Usage (for Ceilometer) have no text alternatives.
  • 1.3.1 Info and Relationships
    • There is no caption element, summary attribute in tables such as instances, volumes, images, so on.
    • There is no scope attribute in th elements.
  • 1.4.3 Contrast (Minimum)
    • text color and background color in the left menu
    • text color and background color in the top menu
    • link color and background color in the main content area
    • text color and background color of the some buttons
  • 2.1.1 Keyboard
    • It's not easy to handle the layered message window by keyboard only.
    • It may be difficult for a blind person to notice this layered error message.
  • 2.4.1 Bypass Blocks
    • There is no mechanism to skip repeated contents such as menu. For example, we can add a link at the top of each page that goes directly to the main content area.
  • 2.4.3 Focus Order
    • The order of navigation doesn't match the visual order in some cases.
    • The focus movement is not restricted to the layered pop-up window.
