This document describes how different WCAG checkpoints help Mobile Web users and how compliance with these checkpoints can help comply with the Mobile Web Best Practices 1.0 (MWBP). For content that already complies with WCAG at different levels, it outlines what may need to be done to comply with all of the MWBP (“Extending from WCAG 1.0 to MWBP 1.0”).

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

This section provides guidance on the “upgrade path” from WCAG 1.0 compliance to MWBP 1.0. What follows is a summary of the detailed information for each success criterion that follows it. For each of the WCAG 1.0 priorities (1, 2 and 3) already achieved, the BPs are classified in three broad categories representing the effort required, labelled for simplicity with keywords (nothing, something, everything):


To summarize, if your content already complies with WCAG 1.0, to achieve compliance with MWBP 1.0, you need to do the following:

Nothing: content already complies with these BPs:

Something: more effort of some kind or a check, to comply with these BPs:

Everything: start from scratch to comply with these BPs:

[Not evaluated yet]. When reviewing the document the following list should be ignored. During document editing, it contains CPs, SCs or BPs not yet evaluated. It is progressively reduced as items are studied and moved to the “something”, “nothing” and “everything” lists. It will not appear in the finished document.

Addressing MWBP 1.0 Best Practices

MWBP 1.0 Best Practices

List of best practices described in detail:

MWBP 1.0: Provide a text equivalent for every non-text element.

No further effort is required. [1.1 Provide a text equivalent for every non-text element (e.g., via "alt", "longdesc", or in element content)...] ensures compliance with this best practice.
