detailed reports in appendices

Results

As described in "Examine pages using graphical browsers" in Preliminary Review of Web Sites for Accessibility.

Turn off images, and check whether appropriate alternative text for the images is available.
The important images are in CSS background, without "alt" text
Turn off the sound, and check whether audio content is still available through text equivalents.
No references
Use browser controls to vary font-size: verify that the font size changes on the screen accordingly; and that the page is still usable at larger font sizes.
The font size changes on the screen accordingly on all testing browsers and the page is usable
Test with different screen resolution, and/or by resizing the application window to less than maximum, to verify that horizontal scrolling is not required (caution: test with different browsers, or examine code for absolute sizing, to ensure that it is a content problem not a browser problem).
At 800x600 there is a little horizontal scrolling
Change the display color to gray scale (or print out page in gray scale or black and white) and observe whether the color contrast is adequate.
In gray scale color contrast is adeguate
Without using the mouse, use the keyboard to navigate through the links and form controls on a page (for example, using the "Tab" key), making sure that you can access all links and form controls, and that the links clearly indicate what they lead to.
Complete access to all links with keyboard navigation

Results: There is a problem with important content images that are only in CSS background and a little, very little horizontal scrolling

1. Executive Summary

This report describes the conformance of the CityLights Web site with W3C's Web Content Accessibility Guidelines (WCAG) 1.0. The review process is described in Section 5 below and is based on the W3C's Conformance Evaluation method as described in Evaluating Web Sites for Accessibility.

Based on this evaluation, the CityLights Web site is close to meeting WCAG 1.0, Conformance Level Double A. Detailed review results are available in Section 6 below. Resources for follow-up study are listed in Section 7 below. Feedback on this evaluation is welcome.

2. Background about Evaluation

Conformance evaluation of Web accessibility requires a combination of semi-automated evaluation tools and manual evaluation by an experienced reviewer. The evaluation results in this report are based on evaluation conducted on the following date: February 7, 2006. The Web site may have changed since that time. Additional information on the evaluation process is available in Evaluating Web Sites for Accessibility.

WCAG 1.0 Priority 1 checkpoints

In General (Priority 1) YesNoN/A
1.1 Provide a text equivalent for every non-text element (e.g., via "alt", "longdesc", or in element content). This includes: images, graphical representations of text (including symbols), image map regions, animations (e.g., animated GIFs), applets and programmatic objects, ascii art, frames, scripts, images used as list bullets, spacers, graphical buttons, sounds (played with or without user interaction), stand-alone audio files, audio tracks of video, and video.   no  
2.1 Ensure that all information conveyed with color is also available without color, for example from context or markup. yes    
4.1 Clearly identify changes in the natural language of a document's text and any text equivalents (e.g., captions).     to implement later
6.1 Organize documents so they may be read without style sheets. For example, when an HTML document is rendered without associated style sheets, it must still be possible to read the document.   no  
6.2 Ensure that equivalents for dynamic content are updated when the dynamic content changes.     n/a
7.1 Until user agents allow users to control flickering, avoid causing the screen to flicker.     n/a
14.1 Use the clearest and simplest language appropriate for a site's content.     n/a
And if you use images and image maps (Priority 1) YesNoN/A
1.2 Provide redundant text links for each active region of a server-side image map.     n/a
9.1 Provide client-side image maps instead of server-side image maps except where the regions cannot be defined with an available geometric shape.     n/a
And if you use tables (Priority 1) YesNoN/A
5.1 For data tables, identify row and column headers.     n/a
5.2 For data tables that have two or more logical levels of row or column headers, use markup to associate data cells and header cells.     n/a
And if you use frames (Priority 1) YesNoN/A
12.1 Title each frame to facilitate frame identification and navigation.     n/a
And if you use applets and scripts (Priority 1) YesNoN/A
6.3 Ensure that pages are usable when scripts, applets, or other programmatic objects are turned off or not supported. If this is not possible, provide equivalent information on an alternative accessible page.     n/a
And if you use multimedia (Priority 1) YesNoN/A
1.3 Until user agents can automatically read aloud the text equivalent of a visual track, provide an auditory description of the important information of the visual track of a multimedia presentation.     n/a
1.4 For any time-based multimedia presentation (e.g., a movie or animation), synchronize equivalent alternatives (e.g., captions or auditory descriptions of the visual track) with the presentation.     n/a
And if all else fails (Priority 1) YesNoN/A
11.4 If, after best efforts, you cannot create an accessible page, provide a link to an alternative page that uses W3C technologies, is accessible, has equivalent information (or functionality), and is updated as often as the inaccessible (original) page.     n/a

WCAG 1.0 Priority 2 checkpoints

In General (Priority 2) YesNoN/A
2.2 Ensure that foreground and background color combinations provide sufficient contrast when viewed by someone having color deficits or when viewed on a black and white screen. [Priority 2 for images, Priority 3 for text]. yes    
3.1 When an appropriate markup language exists, use markup rather than images to convey information.     n/a
3.2 Create documents that validate to published formal grammars. yes    
3.3 Use style sheets to control layout and presentation. yes    
3.4 Use relative rather than absolute units in markup language attribute values and style sheet property values. yes    
3.5 Use header elements to convey document structure and use them according to specification. yes    
3.6 Mark up lists and list items properly. yes    
3.7 Mark up quotations. Do not use quotation markup for formatting effects such as indentation.     n/a
6.5 Ensure that dynamic content is accessible or provide an alternative presentation or page.     n/a
7.2 Until user agents allow users to control blinking, avoid causing content to blink (i.e., change presentation at a regular rate, such as turning on and off).     n/a
7.4 Until user agents provide the ability to stop the refresh, do not create periodically auto-refreshing pages.     n/a
7.5 Until user agents provide the ability to stop auto-redirect, do not use markup to redirect pages automatically. Instead, configure the server to perform redirects.     n/a
