Prüfschritt | Warum wird das geprüft? | |||||||||||||||||||||||||||||||||||||||||||||||
9.1.3.2 Sinnvolle Reihenfolge | Screenreader lesen die Elemente, die auf dem Bildschirm in der Fläche angeordnet sind, nacheinander vor - und zwar in der Reihenfolge, in der sie im Quellcode stehen. Die Reihenfolge der Elemente muss also gut verständlich und nutzbar sein. | |||||||||||||||||||||||||||||||||||||||||||||||
9.2.4.3 Schlüssige Reihenfolge bei der Tastaturbedienung | Die Bedienung soll geräteunabhängig möglich sein. Das bedeutet: Sie muss sowohl mit einem Zeiger (Maus, Touch-Geste) als auch mit der Tastatur möglich sein. Auch adere Eingabeformen, etwa die Spracheingabe oder Schaltersteuerung, sind auf eine gute Tastaturbedienbarkeit und eine sinnvolle Fokusreihenfolge angewiesen. Probleme gibt es meistens mit der Tastaturbedienung, denn die Mehrzahl der Webnutzenden arbeitet mit der Maus, daher wird oft nur an sie gedacht. Auf die Tastaturbedienbarkeit angewiesen sind zum Beispiel viele motorisch eingeschränkte Menschen oder Blinde. Bei einer nicht nachvollziehbaren Fokusreihenfolge laufen Nutzende Gefahr, die Orientierung zu verlieren, die Tastaturbedienbarkeit kann dadurch erheblich beeinträchtigt sein. Manche Seiten präsentieren mittels JavaScript dynamische Inhalte. Rückmeldungen bei fehlerhaften Formular-Eingaben werden beispielsweise dynamisch unter dem Feld angezeigt oder Dialoge werden eingeblendet. Während diese Änderungen der Seite für sehende Nutzende unmittelbar wahrnehmbar sind, werden sie von Screenreader-Nutzenden gar nicht oder erst mit Verzögerung wahrgenommen. Werden weitere Elemente über DOM-Scripting in den Quellcode einer Seite dynamisch eingefügt (d.h. ohne dass die Seite neu lädt), soll diese Einfügung unterhalb des auslösenden Elements geschehen, damit Screenreader hinzugefügte Elemente bemerken und vorlesen. Werden Elemente an anderer Stelle im DOM eingefügt, etwa am Seitenende (das ist oft bei Modalen Dialogen der Fall), müssen Scripte für ein sinnvolles Fokusmanagment sorgen und damit eine sinnvolle Fokusreihenfolge gewährleisten. | |||||||||||||||||||||||||||||||||||||||||||||||

Test step | Why is this checked? | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
9.1.3.2 Sensible order | Screen readers read the elements arranged in the area on the screen one after the other in the order in which they appear in the source code. Thus, the order of the elements must be easily understandable and usable. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
9.2.4.3 Consecutive order in keyboard operation | The operation should be possible independent of the device. That means: It must be possible with the mouse as well as with the keyboard. Because also other special devices behave like a mouse or like a keyboard. There are mostly problems with the keyboard operation, because the majority of the web users works with the mouse, therefore often only the mouse is thought of. Many people with motor impairments or blind people, for example, are dependent on keyboard operability. If the order of links and form elements is not comprehensible, keyboard usability can be significantly impaired. Some pages use JavaScript to present dynamic content, such as feedback for incorrect form input or news teasers that alternate. While dynamic changes to the page are immediately noticeable to sighted users, they are often not noticed at all or only with a delay by screen reader users. When additional elements are inserted into the source code of a page via DOM scripting after the page has been loaded, this insertion should be below of the triggering element, so that screen readers notice and read aloud added elements. In some cases, if understandable in context, they may be inserted or modified further down the page (i.e., not immediately after the triggering element). If elements are inserted elsewhere, for example at the bottom of the page (this is often the case with modal dialogs), scripts must ensure that a sensible focus order is created and that blind users also notice the change. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

For blind users or for users who disable loading of graphics for faster access times, graphics are not accessible. The text alternative then takes the place of the graphic, it should replace the graphic.
Icon Fonts are fonts that contain icons instead of letters. They are included via CSS and are either not output by assistive technologies or a Unicode equivalent is rendered, which does not convey the meaning in context.
Visually impaired users often enlarge page content using the zoom feature available in popular desktop browsers. Using responsive design with CSS media queries, websites should support high zoom usage by dynamically adjusting the page break.
Responsive page layouts rearrange content blocks. Multi-column content is usually paginated so that it is arranged in a single column underneath each other when zoomed in heavily. For continuous text, new line breaks with shorter lines are also created.
The advantage: users only have to scroll in one direction when reading (in western languages: vertically). On the other hand, if lines do not wrap when zoomed in, users are forced to scroll back and forth horizontally while reading each line, which greatly impairs and slows down the absorption of the content.
Visually, web page content is structured by headings. Thanks to this structuring, the user knows what belongs together, can easily overview the contents of the web page and access specific content that interests him.
If form fields are labeled in a meaningful way, users can recognize and use them.
Language input users can activate controls such as links, buttons, or input fields by saying the visible name, even in conjunction with commands (e.g. Click "Submit" button). If the visible label does not appear in the stored accessible name of the control (i.e., the text that is programmatically determined as the label), the control may not be activated or may be activated only indirectly using speech input.
Sometimes controls have an accessible name that differs from the visible label because it is defined by non-visible attributes such as aria-label
or via attributes that are only displayed when the mouse is used, such as title
. For example, the visible label "Accept T&C" could be replaced by the stored accessible name "Accept General Terms and Conditions". When voice input users now dictate click "Accept T&C", this text does not appear in the accessible name, so the input fails.
Sometimes hidden text is used to extend visible labels, often with the intention of helping assistive technology users. This is fine if the visible caption is included throughout the accessible name, preferably at the beginning.
Errors often occur during form input: Users make mistakes or skip required entries.
When the service checks user input, it should identify fields with incorrect or missing input. This makes it easier for users to correct input.
If visible labels are provided, users know what inputs are expected. Errors can be avoided.
Placing labels directly in front of or above the input field conforms to standard design conventions. Even in partial views (e.g. in magnification software), it quickly becomes clear which labeling belongs to which field.

BegründungDie Friedrich-Schiller-Universität Jena ist bemüht, alle Angebote barrierefrei zugänglich zu machen und alle aktuell nicht barrierefreien Inhalte nachzubessern. Auf Grund der technischen Struktur ist es mit der derzeit aktuellen Umsetzung jedoch nicht möglich, allen Anforderungen der Barrierefreiheit vollständig gerecht zu werden. Wir sind bemüht dies zukünftig nachzubessern. |

ReasonThe Friedrich Schiller University Jena endeavors to make all offers accessible and to improve all currently non-accessible content. Due to the technical structure, it is not possible with the current implementation to fully meet all accessibility requirements. We are trying to improve this in the future. |
