»Do not read ›Understanding WCAG‹.

In fact, do not read WCAG 2.

Web Accessibility is about people, not about guidelines.«

(Shawn Henry, W3C WAI)

Percievable

1. Provide equivalent alternatives to auditory

and visual content.

1.1 Provide a text equivalent for every non-text element.

1.1.1 Non-text Content: All non-text content that is presented to the user has a text alternative

that serves the equivalent purpose

G94: Providing short text alternative for non-text content that serves the same purpose and presents the same information as

the non-text content [...] Examples: A search button uses an image of a magnifying glass. The text alternative is "search" and not

"magnifying glass".
