Web accessibility

Web accessibility means that our websites can be used by everyone – including visitors with visual, hearing or motor impairments, or who are colour blind or dyslexic. 

For a website to be considered accessible, it must be optimised for use by various tools, such as screen readers or eye trackers. 
As a public organisation, we must comply with the Web Accessibility Act. 

It is your responsibility as a web editor at SDU to ensure that your pages on sdu.dk, MitSDU and SDUnet are accessible. This also applies to images and files in the media library. 

SDU Communications – Web ensures that SDU’s accessibility statement is completed and available in the footer of our pages. 

The features in Sitecore help us when we need to make the text on a page accessible to screen readers or specialised keyboards.

Images should have ALT captions 

A screen reader can only explain what’s happening in an image if the editor has filled in the ALT text when uploading the image to the media library. 

The ALT text should describe what is happening in the image so that users who are blind get the same information as users who can see the image. You do not need to type ‘Image of...’ – the screen reader will do that automatically. 
If the image is just for decoration and has no meaning, you don’t need to write anything. 
If the image is to be used on both the Danish and English pages, create two versions in the media library so that you can write an ALT text in both languages. 

Do not write on the image itself – the screen reader can’t read it.

If you use image carousels, animations or similar, the user must be able to stop them. The Accessibility Act emphasises that it must be possible to stop moving images.

Videos should be subtitled 

All videos must have subtitles and are preferably audio described. 
An audio-described video has an extra soundtrack, in which a narrator’s voice describes what is happening in the visuals of the video. The voice explains who, where and what – basically everything that isn’t evident from the dialogue. For instance, a smiling gaze between two people, a drone hovering in the air or a beautiful sunset. This allows users to follow the video even if they can’t see the actual footage.

Do not use auto-play on video, and make sure you can pause, stop and remove audio on a video.

In general, avoid PDFs. They are difficult to make accessible and they don’t work well on small screens.  
Whenever possible, create PDFs for regular web pages only.  
Learn how to make PDFs accessible if the content cannot be communicated in any other way.
