Thematics

  1. 1. Images

    Give each image conveying information a relevant text alternative and a detailed description if necessary. Replace images of text with styled text when possible.

  2. 2. Frames

    Provide each inline frame with a relevant title.

  3. 3. Colors

    Do not provide information through color only, and use sufficient color contrasts.

  4. 4. Multimedia (Soon)

    If necessary, provide each time-based media with relevant text transcript, synchronized captions and a synchronized audio description. Provide each non time-based media with a relevant text alternative. Provide control features for each time-based and non time-based media through a keyboard and ensure that they are compatible with assistive technologies.

  5. 5. Tables

    Provide each complex data table a relevant title, clearly identify header cells, use a relevant mechanism to associate data cells with header cells. Ensure that each layout table is correctly linearized.

  6. 6. Links

    Provide explicit link text, through context information if needed, and use the link title as sparsely as possible.

  7. 7. Scripts

    Provide, if necessary, each script with a relevant alternative. Make each script controllable at least through a keyboard and a mouse, and ensure that it is compatible with assistive technologies.

  8. 8. Mandatory elements

    Check that each Web page has a valid source code according to the document type, a relevant title and a default human language identification. Check that tags are not used for presentation only, that changes in human language and changes in the reading direction are specified.

  9. 9. Information structure

    Use headings, landmarks, lists, abbreviations and quotes to structure information. Ensure that the document outline is coherent.

  10. 10. Presentation of information

    Use style sheets to control information presentation. Check for the effect of font size increasing on readability. Ensure that links can be correctly identified, that focus is specified, that line spacing is sufficient, and give the user the ability to control text justification. Ensure that hidden texts are correctly rendered and that information is not conveyed only by an element's shape, size or location.

  11. 11. Forms

    For each form, associate each field with its label, group fields in similar blocks of information, structure selection lists in a consistent way, give each button an explicit label. Check that input help is available, ensure that the input control is accessible and that the user can control financial, legal or personal data.

  12. 12. Navigation

    Facilitate navigation in a set of pages through at least two different navigation systems (navigation menu, site map or search engine), a breadcrumb trail and the indication of the active page in the navigation menu. Identify groups of important links and the main content area, and provide the ability to avoid them through skip links. Ensure that tabbing order is consistent and that the page does not contain keyboard traps.

  13. 13. Consultation

    Check that the user can control the refresh processes, sudden changes in luminosity, openings of new windows and moving or blinking content. Specify when a content opens in a new window and provide information regarding viewing of files to download. Do not make the completion of a task rely upon a time limit except if it is essential and ensure that entered data is retrieved after an authenticated session has expired. Ensure that unusual phrases and jargon are made explicit. Provide accessible versions or make downloadable documents accessible.
