# Using null `alt` text and no `title` attribute on `img` elements for images that assistive technology should ignore

ID: H67

Technology: html

Type: Technique

## When to Use

HTML documents that load images.

## Description

The purpose of this technique is to show how images can be marked so that they can be ignored by assistive technology.

If no `title` attribute is used, and the `alt` text is set to null (i.e., `alt=""`) it indicates to assistive technology that the image can be safely ignored.

Having a "null" `alt` attribute is not the same as having no `alt` attribute.

## Examples

### Inserting a decorative image on a Web page

    <img alt="" src="squiggle.gif" height="20" width="20">

## Tests

### Procedure

For each image that should be ignored:

1. Check that `title` attribute is either absent or empty.
2. Check that `alt` attribute is present and empty.

### Expected Results

- #1 and #2 are true
