Goal
- Enable users in environments where the CSS fonts used to display symbols are not reproduced (text browsers, screen readers or browsers with the images disabled) to understand the meanings of those symbols.
- Enable bots to exploit the information carried by those symbols (to reference, index and perform machine translation on the alternatives).
- Improve the accessibility of content for people with disabilities.
- Improve the way content is taken into account by search engines and indexing tools.
Implementation
Provide hidden content for display via CSS for all information conveyed by the use of a specific font.
Control
Examine the code directly to check that each icon displayed through a font has an alternative in the HTML content.
