Accessibility digest

Introduction

How accessible is the Geohazards International web page at https://www.geohaz.org/?

This digest can help answer that question. Nine different tools (Alfa, ASLint, Axe, Equal Access, HTML CodeSniffer, Nu Html Checker, QualWeb, Testaro, and WAVE) tested the page to check its compliance with their accessibility rules. In all, the tools define about 915 rules, which are classified here into about 300 accessibility issues.

The results were interpreted to yield a score, with 0 being ideal. The score for this page was 3581, the sum of 600 for the count of issues, 2385 for specific issues, 533 for tool-by-tool ratings, 0 for the page preventing tools from running, 63 for browser warnings, and 0 for delayed page responses.
