No, it doesn't. The document says, under conformance: Conformance Level "Triple-A": all Priority 1, 2, and 3 checkpoints are satisfied; Appendix A doesn't list any checkpoints. > I guess my question is: Do IE-related CSS hacks cause a document to fail AAA > (or A/AA for that matter) Accessibility compliance? Maybe and no. There are IE-related CSS hacks that are valid, and others that are not. The valid ones don't cause it to fail any checkpoint, as far as I know. Guideline 3 says "Use markup and style sheets and do so properly" and you could make a case that invalid CSS is not "using style sheets properly". Checkpoint 3.2 says "Create documents that validate to published formal grammars.", but it can be argued that a style sheet is not a document. Meanwhile, WCAG 2.0 makes no requirement that CSS be valid (and when refers to 'markup' rather than 'documents'). -- David Dorward http://dorward.me.uk ******************************************************************* List Guidelines: http://webstandardsgroup.org/mail/guidelines.cfm Unsubscribe: http://webstandardsgroup.org/join/unsubscribe.cfm Help: memberh...@webstandardsgroup.org *******************************************************************
