Actual Results

Colors green for added line, red and strikethrough for deleted line and blue for formatting change are used to identify the comparison difference in the Key and on the main page content visually; however, these changes or updates shown on the page are not announced by the screen reader.

This will make it difficult for screen reader users to distinguish changes or updates made within the text of the page and understanding the Key.

Expected Results

All content changes must be programmatically determinable by assistive technologies. Screen reader users should receive clear context about what was modified without relying on visual formatting or color.

In this scenario, we can apply following changes -

• Deleted text should be conveyed as deleted using semantic <del> element, or visually-hidden text like <span class="sr-only"> Deleted: </span>.
• Added text should be conveyed as inserted/added using semantic <ins> element, or visually-hidden text like <span class="sr-only"> Added: </span>.
• Formatting changes can be indicated by the visually-hidden text like <span class="sr-only"> Formatting changed: </span>).

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available.
