4. Priorities
Each checkpoint has a priority level assigned by the Working Group based on the checkpoint’s impact on accessibility. [Priority 1] A Web content developer must satisfy this checkpoint. Otherwise, one or more groups will find it impossible to access information in the document. Satisfying this checkpoint is a basic requirement for some groups to be able to use Web documents. [Priority 2]3. How the Guidelines are Organized
This document includes fourteen guidelines, or general principles of accessible design. Each guideline includes: * The guideline number. * The statement of the guideline. * Guideline navigation links. Three links allow navigation to the next guideline (right arrow icon), the previous guideline (left arrow icon), or the current guideline’s position in the table of contents (up arrow icon). * The rationale behind the guideline and some groups of users who benefit from it. * A list of checkpoint definitions.2. Themes of Accessible Design
The guidelines address two general themes: ensuring graceful transformation, and making content understandable and navigable. 2.1 Ensuring Graceful Transformation By following these guidelines, content developers can create pages that transform gracefully. Pages that transform gracefully remain accessible despite any of the constraints described in the introduction, including physical, sensory, and cognitive disabilities, work constraints, and technological barriers. Here are some keys to designing pages that transform gracefully:1. Introduction

- They may have difficulty reading or comprehending text.
- They may not have or be able to use a keyboard or mouse.
- They may have a text-only screen, a small screen, or a slow Internet connection.
