BioCyc

Summary

This report reflects the findings of a high-level assessment of the BioCyc platform for its conformance with the W3C Web Content Accessibility Guidelines version 2.1 (WCAG 2.1).  

Overall, there are very few issues with the BioCyc platform. There are, however, some essential WCAG 2.1 A and AA level requirements that need to be met for compliance around navigation and nested controls. Additionally, there are a few other issues with color contrast, alt text, and ARIA implementation. Below are the most critical issues to address to improve system compliance.

Top 3 Issues

  1. Site Navigation: The navigation menu is inaccessible to keyboard users which blocks them from being able to fully navigate the site. Several of the pages have dual-axis scrolling that cuts off content and makes navigation within the page more difficult. The focus order on the search results page does not follow the logical flow of content and should be remediated to reduce cognitive load.
  2. Nested Controls: There is a significant issue on the search results page where the right panel has several nested controls. This can lead to serious issues with screen readers and interactivity.
  3. Color Contrast: There are minor color contrast issues between the orange buttons and their backgrounds. Interactive elements need to meet at least 3:1 contrast with the background and 4.5:1 contrast with their text.
