Web Content Accessibility Guidelines
(WCAG), offering more comprehensive accessibility measures for a broad range

Table of contents navigation
Allows you to navigate directly to chapters, sections, or non‐text items
through a linked table of contents, reducing the need for extensive scrolling.
Index navigation
Provides an interactive index, letting you go straight to where a term or
subject appears in the text without manual searching.
Reading Order & Textual Equivalents
Single logical reading order
You will encounter all content (including footnotes, captions, etc.) in a clear,
sequential flow, making it easier to follow with assistive tools like screen readers.
Short alternative textual descriptions
You get concise descriptions (for images, charts, or media clips), ensuring you do
not miss crucial information when visual or audio elements are not accessible.
Visualised data also available as non-graphical data
You can access graphs or charts in a text or tabular format, so you are not
excluded if you cannot process visual displays.
Visual Accessibility
Use of colour is not sole means of conveying information
You will still understand key ideas or prompts without relying solely on
colour, which is especially helpful if you have colour vision deficiencies.
Use of high contrast between text and background colour
You benefit from high‐contrast text, which improves legibility if you have
low vision or if you are reading in less‐than‐ideal lighting conditions.
