Decision level

Semi-Decidable

Algorithm

Selection

Set1

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)

Process

The selection handles the process.

For each element of Set1 raise a MessageA

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

Analysis

Not Applicable

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

re-Qualified

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

Notes

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.
