This tab shows accessibility issues, indicating problems for older users, people with disabilities or accessibility needs. Automated testing cannot detect all accessibility issues, so should be used alongside human testing.

| | An image with a null ALT attribute should not have TITLE or ARIA label attributes. | WCAG 2.0 A F39 Section 508 (2017) A F39 | 1 pages |
|
If the image should be voiced use a descriptive ALT attribute.
If the image is purely decorative remove any TITLE and ARIA label attributes. Impact on users: - JAWS : Ignores all images with ALT=''.
- NVDA : Reads some images with ALT='' and a TITLE or ARIA label.
- WindowEyes : Reads images with ALT='' and a TITLE or ARIA label.
- VoiceOver : Reads images with ALT='' and a TITLE or ARIA label.

| | Each A element must contain text or an IMG with an ALT attribute. | WCAG 2.0 A F89 Section 508 (2017) A F89 | 2 pages |
|
Add text to the link, or ALT text if the link contains an image. If there is no link text or the ALT text is blank, screen readers have nothing to read, so read out the URL instead.
The TITLE attribute on the A element doesn't work in:
- WindowEyes 8.4 with IE11 (the link HREF is read instead)
- VoiceOver on OSX 10.9 (the image filename is read instead)

| | Identify row and column headers in data tables using TH elements, and mark layout tables with role='presentation'. | Section 508 (2000) 1194.22 (g) WCAG 2.0 A F91 Section 508 (2017) A F91 | 2 pages |
|
Data tables allow screen reader users to understand column and row relationships.
Layout tables read cells as a series of unrelated paragraphs with no tabular structure.
Without TH or ROLE, screen readers apply heuristics to decide whether a table is a layout table or data table.
These heuristics vary greatly between screen readers, and are affected by browser being used, window size,
and font size (so the outcome is very unpredictable without TH or ROLE).
If a data table has headers marked up using TD, then change these to TH.
If a data table has no headers, add TH elements describing each row and/or column.
If the table is only used for layout add role='presentation' to the TABLE element. Impact on users: - JAWS Reading: Treats tables without TH and ROLE as layout tables if the table contains cells above or below certain pixel sizes. This measurement is affected by browser window size, browser font size, and the browser used.
- NVDA Reading: Applies a 'layout table' heuristic to tables without TH and ROLE which varies depending on the browser used and on the window size in some circumstances.
- VoiceOver Safari OSX 10.9 Reading: Uses a sophisticated heuristic on tables without TH and ROLE, which is similar (but not identical) to the heuristic used by NVDA with Firefox.

|
Add an ALT attribute describing each image, which screen readers read aloud.
Spacer images and purely decorative images should use ALT=''. Impact on users: - NVDA 2015.2 FF40 Windows 7 Reading: Image ignored.
- JAWS 16.0.4350 FF40 Windows 7 Reading: Image ignored.
- WindowEyes 8.4 IE11 Windows 7 Reading: Image ignored.

|
Add a TITLE attribute to each FRAME and IFRAME element (e.g. TITLE="Main Content"). Without a TITLE some screen readers read out the FRAME filename, which is usually meaningless.
IFRAMEs with no title cause problems in:
- JAWS 14 and 15 with Firefox (the frame SRC filename is read instead)
- VoiceOver on OSX 10.9 (a meaningless title like "Frame twelve" is read out)

| | Provide a way to skip repetitive navigation links. | Section 508 (2000) 1194.22 (o) | 1 pages |
|
Without skip links, keyboard users must tab through the navigation links to get to page content.
Headings and landmarks allow screen reader users to skip navigation, but don't work for other keyboard users.
Add a "Skip to Content" link at the start of the document hidden offscreen by CSS, and made visible on focus, so it's available to keyboard and screen reader users:
<a class="accessible" href="#main">[Skip to Content]</a>

|
Remove the text-decoration:none property from your link styles, or add other non-color style attributes to visually distinguish links. | | |

|
A programmatically determined name allows screen readers to tell the user what the control does. To add a name do one of the following:
- Use a LABEL element with the FOR attribute set to the ID of the form control
- Wrap a LABEL element around the form control
- Add a TITLE attribute
- Add an ARIA-LABELLEDBY attribute (not supported in all screen readers)
- Add an ARIA-LABEL attribute (not supported in all screen readers)

| | This form has fields without LABEL elements or TITLE attributes. | Section 508 (2000) 1194.22 (n) | 2 pages |
|
Screen readers use LABEL elements or TITLE attributes to describe form fields to non-sighted users.
Without these, forms are very hard to use with a screen reader.
Forms designed to be completed online shall allow people using assistive technology to access the information, field elements, and functionality required for completion and submission of the form, including all directions and cues. | | |

| | Use relative rather than absolute units in CSS property values. | WCAG 2.0 AA 1.4.4 Section 508 (2017) AA 1.4.4 | 2 pages |
|
Absolute units are CM, MM, IN, PC and PT. When used with fonts PX is also considered an absolute unit,
because it isn't relative the user's preferred font size.
Low-vision users, and a lot of people over 50, increase the browser default font size to make text
easier to read. Absolute units ignore this user choice.
Relative units like EM and percentages "stretch" according to the screen size and/or
user's preferred font size, and work on a large range of devices. | | |
