Test : 10.13.1

Test description :

On each Web page, does each hidden text pass one of the conditions below?

  • The text is not intended to be rendered by assistive technologies
  • The text is made visible on user action on the element itself or on an element before the hidden text

Level : Bronze

Technical description

Scope : page

Decision level : semidecidable




All the hidden text elements. Elements from the DOM with :

  • a not empty text and
  • a "display" css property equals to "none" or a "visibility" css property equals to "hidden", these properties can be inherited from a parent (see Note for more details about the selection)


The selection handles the process.

For each element of Set1 raise a MessageA

Message 1: Hidden text detected
  • code : HiddenTextDetected
  • status: NMI
  • parameter : snippet
  • present in source : yes



Set1 is empty (the page has no textual hidden element)


Set1 is not empty (the page has textual hidden elements)


The visibility of each element of the page is determined while fetching the page, through a javascript script.

If the "display" css property is equal to "none" or the "visibility" css property is equal to "hidden" for an element or one of its parents, this element is seen as hidden.
