13 img elements and/or elements with [role="img"] that are hidden were not evaluated.
Mathematical expressions must be marked up using MathML instead of bitmapped images.
Images used to convey mathematical expressions are not accessible to people with disabilities using assistive technologies.
MathML is a W3C standard for representing mathematical expressions for web technologies and is the most accessible web math format for people using assistive technologies.
MathML has capabilities similar to SVG graphics, providing the abilities to resize and style content without the loss of fidelity of the visual rendering to match the capabilities of people with visual impairments.
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.
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.
