When additional content becomes visible upon receiving pointer hover or keyboard focus (and subsequently becomes hidden when these triggers are removed) it should be dismissible in a manner that allows users to close the content without needing to move the pointer or re-focus. This applies unless the additional content communicates an input error (that has then been addressed) or does not obscure or replace other content.
The primary goal of this success criterion is to allow users to adjust text spacing to improve readability. This approach aims to improve accessibility for users with cognitive disabilities. It does not require all content to meet these exact spacing specifications; rather, it requires that the website remains responsive when users customize their preferred text settings.
