    How to Fix the Problem

    Ensure iframe and frame elements contain the axe-core script.

    The after - function (optional) check is the function that gets called for checks that operate on a page-level basis, to process the results from the iframe elements.

    The pageLevel Ensures iframe and frame elements contain the axe-core script rule, when set to true, is only applied when the entire page is tested. Results from nodes on different frames are combined into a single result.

    Why it Matters

    Without the axe-core script, it is not possible for the tool to perform violation checking on multiple levels of nested iframes.

    Rule Description

    Frames must be tested with axe-core.

    The Algorithm (in simple terms)

    The iframes property, when set to true, tells axe to run inside iframes. This uses both frame and iframe selectors to check for the axe-core script to return a "review item" result.
