# Failure of Success Criterion 1.1.1 due to not marking up decorative images in HTML in a way that allows assistive technology to ignore them

ID: F38

Technology: failures

Type: Failure

## When to Use

HTML

## Description

This describes a failure condition for text alternatives for images that should be ignored by AT. If there is no alt attribute at all assistive technologies are not able to ignore the non-text content. The alt attribute must be provided and have a null value (i.e., alt="" ) to avoid a failure of this Success Criterion.

This describes a failure condition for text alternatives for images that should be ignored by assistive technology (AT). If an image has the attribute role="presentation", it will be ignored by AT. However, if it does not have role="presentation", and if there is no `alt` attribute at all assistive technologies are not able to ignore the image. For decorative images which need to be ignored by AT, either role="presentation" must be used or the alt attribute must be provided and have a null value (i.e., alt="") to avoid a failure of this Success Criterion.

## Examples

- Decorative images that have no `alt` attribute and no `role` attribute

## Tests

### Procedure

For any `img` element that is used for purely decorative content:

1. Check whether the element has no `role` attribute or has a `role` attribute value that is not `presentation`.
2. Check whether the element has no `alt` attribute or has an `alt` attribute with a value that is not null.

### Expected Results

- If check #1 and #2 are true, this failure condition applies and content fails the Success Criterion.
