Accessibility deprecated


Web accessibility aims at helping users with disabilities to access the web, i.e. perceiving and interacting with web sites or web-based applications. In order to offer everyone – with or without disabilities – the best possible user experience, we continually strive to meet the Level AA conformance as defined by the Web Content Accessibility Guidelines 2.1.

Accessibility typically covers keyboard support, tab order, focus management, color contrast, semantic markup, WAI-ARIA support, and screen reader support.

We perform screen reader testing with the following typical setups: NVDA with Firefox, JAWS with Internet Explorer and Voiceover with Safari (with accessibility option turned on, i.e. tab highlights each item).

Annual accessibility audits are conducted by the Paciello Group.
