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.
- 3.1.1 Language of Page
- There is no lang attribute on the html element.
