We are continually striving to make our content increasingly accessible and valuable to as broad an audience as possible. Writing for accessibility involves so much more than merely making everything on the page available as text. There’s also the way you organize content and guide readers through a page. Depending on our audience and their country, there may be laws governing the level of accessibility required. At the very minimum, an accessible version of all content should be available. Writing for accessibility means considering users of all mental and physical capacities.
We write for a diverse audience of readers. These readers all interact with our content in different ways. Our goal is to make our content accessible to anyone using a Braille interface, keyboard navigation, or a screen reader. Again, we consider users of all cognitive abilities and write accordingly.
As you write, consider the following:
Part of writing for accessibility is making sure you avoid giving directional instructions. Stay away from any language that requires the reader to see the layout or design of the page. This is helpful for many reasons, including layout changes that occur on mobile devices.
The alt tag is the most basic form of image description. It should be included in all images. The language will depend on the purpose of the image:
Each browser handles alt tags differently, so supplement images with standard captions whenever it’s possible.
Closed captioning or transcripts must be available for all videos. Whatever information you’ve presented in video format should also be available in other formats.
Create visuals that feature high contrast between the font and background colors. The tools available in the resources section should help with picking available colors.
Avoid using images as the primary form of communication. They may not load or may not be seen. If it’s possible to convey through writing the same information found in an image, go that route.
