FACT: Web pages that contain duplicate IDs can cause problems in screen readers.

If two or more elements on the same page share the same ID, this can cause problems in screen readers which use IDs for labeling controls and table headings.

It can also cause problems in JavaScript methods like getElementById and querySelector, which behave inconsistently when duplicate IDs are present.

Change the IDs so all are unique for each element.
