Rule ID Widget 10
Definition Range widget must have value between minimum and maximum values, or have an indeterminate state.
Purpose
  • Range roles identify a value between a minimum or maximum value and whether the value can be changed by the user (e.g. scrollbar, slider or spinbutton).
  • Screen readers typcially render the value of a range widget as a percentage of the total range defined by the minimum and maximum values.
  • aria-valuetext can be used to render an alternative to the percentage when a numerical values and/or a units of measure are more descriptive.
  • Some range roles (e.g. progress and spinbutton) allow an unknown current value indicating indeterminate or no current value.

Techniques
  • Use the aria-valuenow attributes numerical value must be in the range defined by aria-valuemin and aria-valuemax.
  • Screen reader typically render the slider value as a percentage, requiring a valid aria-valuenow attribute.
  • Use the aria-valuetext to provide an alternative to the percentage typically spoken by assistive technologies (e.g. "32 dollars", "78 degrees")
  • For most range roles, if aria-valuemin is not defined it's default value is 0.
  • For most range roles, if aria-valuemax is not defined it's default value is 100.

Column Definitions

Element Identifier
Information about the element associated with the result.
The information typically includes the tag name, accessible name or other information related to the rule requirements.
"Page" means that the result applied to the page. For example, the rule "One main landmark on the page" is a page level rule.
Element Position
The element position is based on the DOM order of elements in the page.
The element position maybe useful in helping to locate a specific element on the page evaluated (e.g smaller numbers are typically toward the beginning of a page and larger numbers typically toward the end of a page).
Element position 1 is the first element.
The highest element position is the last element.
Element position values for most rule/page results will not be consecutive since a rule only applies to a sub set of elements found on a page.
