If your content already meets Web Content Accessibility Guidelines 1.0, this page describes what needs to be done to meet all the Mobile Web Best Practices (MWBP). WCAG 2.0 was approved in [future date] and W3C encourages organizations to focus on WCAG 2.0 instead of only WCAG 1.0..

Summary of work required to make content that meets WCAG 1.0 also meet MWBP

Compliance with WCAG 1.0 helps go some way towards achieving compliance with some of the MWBP. This section provides a summary of these BPs. There are two possible levels of effort required, labelled for simplicity with the keywords nothing, something and everything. To summarise, if your content already complies with WCAG 1.0, to achieve compliance with the MWBP, you need to do the following:

Note on inconsistent links: Links in the “something” and “nothing” sections point to within this page. Links in the “everything” section point to the Recommendation. REVIEW NOTE: Is this too confusing? Suggestions for better ways to do it?

Nothing: Content already complies with this provision so no further effort is necessary. The list is provided for completeness. Links in this section point to the relevant Recommendation.

Something: More effort of some kind is necessary to comply with the provision. What is required is explained in the following section. For each there is a list of the provisions that may provide some compliance or are in some way related. There is no direct correspondence between one provision and another. In some cases, it may be necessary to make an extra effort or to consider a more diverse range of user needs. In these cases, the word “possibly” is used. In other cases scope may be different, giving partial compliance. In these cases the word “partially” is used. BP links in this section point to the detail section below; checkpoint links links in this section point to the WCAG 1.0.

Everything: For all other BPs, WCAG 1.0 does not ensure compliance and it will be necessary to do the work involved. These BPs are not related to any WCAG 1.0 checkpoints.

Addressing Mobile Web Best Practices

This section deals with each of the best practices which WCAG 1.0 helps with meeting. For each BP, the section title is that of the BP. This is followed by a list of the checkpoints that can help meet it.

[ACCESS_KEYS] Assign access keys to links in navigational menus and frequently accessed functionality

[BACKGROUND_IMAGE_READABILITY] When using background images make sure that content remains readable on the device

[COLOR_CONTRAST] Ensure that foreground and background color combinations provide sufficient contrast

[CONTROL_POSITION] Position labels so they lay out properly in relation to the form controls they refer to

[FONTS] Do not rely on support of font related styling

[NAVBAR] Provide only minimal navigation at the top of the page

[PAGE_SIZE_USABLE] Divide pages into usable but limited size portions

[PAGE_TITLE] Provide a short but descriptive page title

[TABLES_ALTERNATIVES] Where possible, use an alternative to tabular presentation

[TABLES_LAYOUT] Do not use tables for layout
