Visual: Web Accessibility Perspectives: Understandable Content

Audio: Instead of saying: "To postulate a conceit more irksome than being addressed in sesquipedalian syntax is adamantine", it is better to say: "Being spoken to in unnecessarily long and complicated language is a pain".

Visual: Two people are trying to follow instructions on a cooking website using lots of text with no illustrations or structure.

Audio: Yet many websites lack structuring using headings, lists and separation. Or they use overly complex language, jargon, and unexplained acronyms.

Visual: They are looking up words in a dictionary to understand the recipe.

Audio: It makes them difficult and unappealing to use for many people, including non-native speakers, and makes them unusable for people with cognitive and learning disabilities.

Visual: They are confused and frustrated by the website.

Audio: Web accessibility: Essential for some, useful for all.

Visual: They search and find a different cooking website with more structured text and illustrations.
