The Early Intervention Foundation follows W3C’s Web Content Accessibility Guidelines (WCAG) 1.0 standards to AA level. All pages use structured, semantic XHTML. Visual styling is provided by Cascading Style Sheets (CSS), and enhanced user interaction is provided by JavaScript.

The Early Intervention Foundation is fully accessible for users without CSS or JavaScript. A text based alternative is provided where images are used to show relevant text content.

Font sizes

Modern browsers support either text resizing or page zooming, to allow users to increase the size of essential page content.

Microsoft Internet Explorer 6 does not support W3C standards with regard to text sizing. It is recommended that users with text resizing upgrade to a standards-compliant browser which provides text resizing or zooming.
