A.23 WCAG 2.1 Success Criterion 3.1.4 − Abbreviations

Wherever abbreviations are used, provide a way for the user to understand what these abbreviations stand for and their meaning. What may seem obvious to one person may be meaningless to another.

Before Rectification

The acronym "UCC" should not be coded like the example displayed above. A screen reader will try to read the letters U-C-C like a word which may be difficult to understand.

After Rectification

When an acronym is used, ensure the code is written as shown above. In this way, screen readers will not read the letters "UCC", it will read the full version of the abbreviation, that is "Unified Communications and Collaboration".
