Accessibility digest

Introduction

How accessible is the Children with Disabilities Fund International web page at https://thecdfi.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 1755, the sum of 520 for the count of issues, 989 for specific issues, 206 for tool-by-tool ratings, 0 for the page preventing tools from running, 40 for browser warnings, and 0 for delayed page responses.
