Title attribute inheritance

If an element has no title attribute, then it inherits it from its parent node, which in turn may inherit it from its parent, and so on.

If this attribute is set to the empty string, it means its ancestors' titles are irrelevant and shouldn't be used in the tooltip for this element.

Accessibility concerns

Use of the title attribute is highly problematic for:

  • People using touch-only devices
  • People navigating with keyboards
  • People navigating with assistive technology such as screen readers or magnifiers
  • People experiencing fine motor control impairment
  • People with cognitive concerns

This is due to inconsistent browser support, compounded by the additional assistive technology parsing of the browser-rendered page. If a tooltip effect is desired, it is better to use a more accessible technique that can be accessed with the above browsing methods.
