+      "description": "Whether out of circumstance, choice, or context people are diverse. As people use different approaches and tools to read and operate interfaces, what the interface offers each user should be comparable in value, quality, and efficiency.",
+      "examples": [
+        {
+          "title": "Content for alternatives",
+          "description": "Having a basic alternative, whether it's alt text, a transcript, audio description, or sign language, makes the content accessible but to be equivalent it needs to capture the essence of the original."

+          "title": "Ergonomic features",

+          "description": "Notifications that appear in an interface are visually obvious but require proactive discovery by screen reader users. A comparable experience for blind users, can be achieved by using a live region. The notification then requires no explicit action on the part of the user."

+      "description": "People are first time users, established users, users at work, users at home, users on the move, and users under pressure. All of these situations can have an impact. For those who already find interaction challenging, such as those with disabilities, this impact may make usage particularly difficult.",

+          "description": "Users may need help when they first encounter a complex form or interaction. This help may become redundant, even distracting, as a user becomes more familiar with the form or interaction. Context sensitive help provides the user with choice as to when they access help and better control over the page."

+      "description": "Familiar interfaces borrow from well-established patterns. These should be used consistently within the interface to reinforce their meaning and purpose. This should be applied to functionality, behavior, editorial, and presentation. You should say the same things in the same way and users should be able to do the same things in the same way.",

+          "description": "Use plain language consistently across platforms including editorial that is relied on by screen reader users such as text alternatives, headings, labels for buttons and so on.

+          "title": "Make it stop",

+        {
+          "title": "Allow zoom",

+      "description": "There is often more than one way to complete a task. You cannot assume what someone's preferred way might be. By providing alternatives for layout and task completion, you offer people choices that suit them and their circumstances at the time.",

+          "title": "Layout",

+        {
+          "title": "Accessible alternatives",
+          "description": "Alternative ways of presenting data, such as data tables for info graphics, should be available to all users, as an option rather than a hidden link just for screen reader users. Accessible alternatives can benefit not just a specific target group but all users as long as we offer the choice."

+      "description": "Interfaces can be difficult to understand when core features are not clearly exposed and prioritised. A site or application may provide lots of information and functionality, but people should be able to focus on one thing at a time. Identify the core purpose of the interface, and then the content and features needed to fulfill that purpose.",

+          "description": "An email application is principally for writing and reading email. The 'compose' button is, therefore, present on all screens, and early in the focus order. The inbox is prioritised over other lists of email, such as 'sent' and 'spam' messages. Less used features such as tagging or organizing email into folders appear later in the focus order, as they will generally only be used when the primary task of reading the email is complete."

+          "title": "Prioritising content",
+          "description": "The primary content on a news article page is the story, therefore it should come before other content, both visually and in the source order. Related content, such as similar articles, should follow it, and unrelated content after that."

+        {
+          "title": "Prioritising editorial",
+          "description": "Editorial for links, headings and buttons should use plain language and put the primary text first. This applies to both visible and hidden text. This makes the text easy to scan both visually and audibly for screen reader users. Plain language also benefits non native speakers and is easier to translate."

+      "description": "Features should add value to the user experience by providing efficient and diverse ways to find and interact with content. Consider device features such as voice, geolocation, camera and vibration API's, and how integration with connected devices or a second screen could provide choice.",
+      "examples": [

+          "title": "Integration with connected devices or second screen",

+          "title": "Integration with platform APIs",
