The Checky Team develops this web site with newest Standards and guidelines, hopefully accessible to all users with all devices. Please use our Help index for a quick overview.
We use XHTML 1.0 Strict and Cascading Style Sheets level 2.0 W3C® Standards for web site development. This is a requirement for accessibility.
We hope we implement all Standards and guidelines to reach WAI Triple-A compliance for this web site. We use different Browser, Checky and some more useful extensions for web site analysis.
Most users browse the web with Microsoft® Windows Internet Explorer as standard Browser. But we know there are tendencies for alternatives. Mozilla, Netscape and Opera have a lot of brand new interesting functions. We highly recommend Firefox with many more useful extensions. For Microsoft® Windows Internet Explorer user, we highly recommend the Web Accessibility Toolbar.
Browser supporting CSS 2.0 media elements automatically choose the best Stylesheet for your device. Mobile devices only supporting XHTML Mobile Profile can point their Browser to the mobile version of this web site.
At this time only Lynx, Mozilla and Opera supports this function without extensions. Firefox can be easily extended with Link Toolbar. With Link elements you have a quick access to the main areas of this web site (Table 1). A web site round trip is available through next and previous definitions in following order:
| Link Element | Area |
|---|---|
| Start | Checky Home |
| Up | Checky Home |
| Previous | Previous chapter in order |
| Next | Next chapter in order |

Please read your Browser Help about how to change Stylesheets. For Microsoft® Internet Explorer users we recommend the Web Accessibility Toolbar. For Mozilla based Browser a Web Developer Toolbar extension is available with this functionality.
We describe images and graphics in the alt attribute of the img element in more detail.
We use tables only for tabular data presentation and not for document layout. A summary and caption provides more information about table of content.
