Make it easier for users to see and hear content including separating foreground and background.
Use of Color
(A)
Color is not used as the only visual means of conveying information, indicating an action, prompting a response, or distinguishing a visual element.
Information conveyed by colors should also be available without color perception, i.e. also highlighted by other means (such as bold or indentation).
Description
Information conveyed by colors should also be available without color perception, i.e. also highlighted by other means (such as bold or indentation).
Example A form contains required and optional fields. The required fields are marked by a red frame only. For people with limited color perception, this may not be sufficient to distinguish required fields from optional fields. In such cases, it would be useful to place an additional symbol next to the fields to indicate the difference between the fields.
Example In an application, red and green areas are displayed next to each other. For people with red-green color deficiency, the two areas cannot be distinguished from each other.
Relevance and applicability
Implementation
-
Accessible layout in Intrexx
In the Intrexx Accessible Layout, the use of appropriate colors is taken into consideration. This is the case, for example, with the colors of buttons and fonts.
-
Generally, colors of elements and fonts can be adapted in Intrexx. Exceptions may exist in terms of diagrams, but even then the colors can be manipulated by the author.
Audio Control
(A)
If any audio on a Web page plays automatically for more than 3 seconds, either a mechanism is available to pause or stop the audio, or a mechanism is available to control audio volume independently from the overall system volume level.
9.1.4.2 Sound can be switched off
Automatic sounds that do not end after three seconds should be capable of being switched off.
Relevance and applicability
This success criterion is not relevant to Intrexx.
No sounds are generated in Intrexx.
Contrast (Minimum)
(AA)
The visual presentation of text and images of text has a contrast ratio of at least 4.5:1. Large-scale text and images of large-scale text have a contrast ratio of at least 3:1.
9.1.4.3 Texts have sufficient contrast
All texts on the page should have sufficient brightness contrast in all states.
Description
The intent of this Success Criterion is to provide enough contrast between text and its background so that it can be read by people with moderately low vision (who do not use contrast-enhancing assistive technology).
Relevance and applicability
Implementation
-
Accessible layout in Intrexx
In the Accessible Layout in Intrexx, the use of sufficient text contrast is considered.
-
The contrast of texts can be adjusted in Intrexx.
Resize text
(AA)
Except for captions and images of text, text can be resized without assistive technology up to 200 percent without loss of content or functionality.
9.1.4.4 Text can be increased to 200 percent
Text can be resized up to 200 percent without loss of content or functionality. At least one of the following requirements shall be met: Using the zoom function of the browser, the font can be enlarged to 200% (this often breaks the page into a new layout). A control at the top of the page can be used to increase font size
Description
The intent of this Success Criterion is to ensure that visually rendered text, including text-based controls can be scaled successfully so that it can be read directly by people with mild visual disabilities, without requiring the use of assistive technology such as a screen magnifier.
Relevance and applicability
Implementation
Intrexx portal and application pages can easily be increased to 200% (using the browser's zoom function). Optimal display is guaranteed. The functionality of the page is fully retained.
Images of Text
(AA)
If the technologies being used can achieve the visual presentation, text is used to convey information rather than images of text.
Graphics should not be used to display fonts. Logos are not included.
Relevance and applicability
This success criterion is not relevant to Intrexx.
Font graphics are not available for use in Intrexx. If they are used, this is the responsibility of the Web author.
Contrast (Enhanced)
(AAA)
The visual presentation of text and images of text has a contrast ratio of at least 7:1.
Description
This success criterion corresponds to the "Texts have sufficient contrast" criterion listed above. However, the contrast requirement is even higher here, so that AAA level is achieved.
With a contrast ratio of 7:1, it compensates for the loss of contrast sensitivity experienced by visually impaired people without assistive technology, and also provides contrast enhancement for color defects.
Relevance and applicability
Implementation
In the Accessible Layout in Intrexx, the contrast is 4.5:1. As a Web author, you can increase the contrast to 7:1 in the "Design" module.

Low or No Background Audio
(AAA)
1.4.7 Low or No Background Audio
1.4.7 Low or No Background Audio
Relevance and applicability
This success criterion is not relevant to Intrexx.
Intrexx does not use background audio.
Visual Presentation
(AAA)
For the visual presentation of blocks of text, a mechanism is available to achieve the following:
- Foreground and background colors can be selected by the user.
- The width is no more than 80 characters or glyphs (40 if CJK).
- Text is not justified (aligned to both the left and the right margins).
- Line spacing (leading) is at least space-and-a-half within paragraphs, and paragraph spacing is at least 1.5 times larger than the line spacing.
- Text can be resized without assistive technology up to 200 percent in a way that does not require the user to scroll horizontally to read a line of text on a full-screen window.
Relevance and applicability
Implementation
Images of a text (No Exception)
(AAA)
1.4.9 Images of Text (No Exception)
1.4.9 Images of Text (No Exception)
If the technologies being used can achieve the visual presentation, text is used to convey information rather than images of text.
Relevance and applicability
This success criterion is not relevant to Intrexx.
Font graphics are not available for use in Intrexx. If they are used, this is the responsibility of the Web author.
Reflow
(AA)
Content can be presented without loss of information or functionality, and without requiring scrolling in two dimensions for:
-
vertical scrolling content at a width equivalent to 320 CSS pixels;
-
horizontal scrolling content at a height equivalent to 256 CSS pixels.
Except for parts of the content which require two-dimensional layout for usage or meaning.
Page content should wrap at a browser window width of 320 CSS pixels (or a browser window width of 1280 CSS pixels and 400% zoom) so that all information and functionality is available without the user having to scroll horizontally.
Relevance and applicability
General implementation
Content in Intrexx breaks, unless the Web author has stored different configurations in the properties of an element. This does not apply to the data tables and images allowed as exceptions, as well as other elements that require a two-dimensional layout.
Non-text Contrast
(AA)
The visual presentation of the following have a contrast ratio of at least 3:1 against adjacent color(s)
User Interface Components Visual information required to identify user interface components and states, except for inactive components or where the appearance of the component is determined by the user agent and not modified by the author;
Graphical Objects Parts of graphics required to understand the content, except when a particular presentation of graphics is essential to the information being conveyed.
